FireConvertApp vs TinyPNG: honest head-to-head

Feature-by-feature matrix

18 rows. We lose on raw compression ratio (their proprietary algorithm is legitimately better on many images), single-task UI polish, 14-year tenure, and the mature API client ecosystem. Orange check = meaningful advantage. Grey = roughly equivalent or depends on the job.

Where TinyPNG beats us

TinyPNG is legitimately great at what it does. A comparison page that pretended otherwise would lose credibility before it earned any. Here's where they're the right tool:

• Proprietary smart-lossy compression is genuinely excellent. This is their flagship claim and it's true. TinyPNG has spent 14 years tuning a single algorithm on a single problem: “make this PNG or JPG as small as possible while looking identical.” On photographic PNGs they regularly beat generic MozJPEG/OxiPNG pipelines by 10–20% at matched perceptual quality. Our /compress-jpeg uses solid open-source encoders with sensible defaults — good, not magic. If pure compression ratio is your hard requirement, they win on that row and we're being honest about it.
• Single-task UI polish — the cleanest compress-an-image page on the web. Drop image, see before/after size and savings %, download. No navigation, no tool picker, no upsell overlay, no ads. Our tool directory is broader and therefore necessarily has more navigation. If your entire use case is “compress this one photo, fast,” TinyPNG's 14 years of iteration on that exact screen still wins on pure UX.
• Mature API with a real client ecosystem. Their API has been in production since 2012. There are battle-tested client libraries for Node, PHP, Python, Ruby, Java, and .NET, plus official plugins for WordPress, Shopify, Magento, and Photoshop. Our v1 API is live and works, but we're newer. For existing production pipelines already wired to TinyPNG, switching is work you might not need to do.
• Brand trust and recognition. TinyPNG is the tool web-perf tutorials name by default when they say “compress your images.” It's on Smashing Magazine's recommendations, it's in every “top image optimization tools” listicle, it's been referenced in Google's own PageSpeed guidance over the years. We're a newer independent startup earning that recognition. If trust from a known name matters to you — especially for a client-facing workflow — that's a real advantage they have.
• CDN / resize / production-pipeline integration. Their Pro tier includes resize-on-the-fly, WebP smart-convert, and S3 upload endpoints designed for production image pipelines. We compress + convert, but we don't host or resize-at-request-time. If your workflow is “CMS upload hook → compress → resize variants → push to CDN,” they're purpose-built for it and we're not.

Where we beat TinyPNG

• Free-tier volume — 50/day vs 20/month. Their free cap is 20 images per month. Ours is 50 per day — roughly 1,500 per month, or 75× more headroom. For anyone compressing more than a handful of images a month — a Shopify seller processing product photos, a blogger doing a weekly image-heavy post, an iPhone user who just dumped a vacation folder — TinyPNG's free tier runs out fast. Ours doesn't.
• Flat-rate pricing — no per-image meter. Their paid tier is $25/month for 500 images, then $0.05 per image after. If you compress 2,000 images in a month that's $25 + $75 = $100. Our Basic plan is $12.99/month flat, unlimited. Our Pro is $29.99 flat. Predictable billing, no meter anxiety, no “should I optimize this extra image or not?” math. For variable monthly workloads, flat-rate is meaningfully cheaper and simpler.
• Broader input formats — HEIC, TIFF, BMP, ICO. TinyPNG accepts JPG, PNG, and WebP only. iPhone photos arrive as HEIC — they can't process it, we can. Scanner output is TIFF; they can't, we can. Favicons are ICO; they don't generate them, we do. For real-world image workflows where files arrive in whatever format the source device chose, broader input matters.
• Format conversion, not just compression. TinyPNG compresses; it doesn't convert between formats. Our /compress-jpeg and the full conversion matrix handle both jobs — compress AND convert JPG↔PNG↔WebP↔AVIF↔HEIC in one shot. Cutting two trips to two tools down to one is meaningful time savings for repeat workflows.
• PDF tools — merge, split, compress, convert. TinyPNG is image-only by design. We ship PDF merge, compress, split, rotate, PDF↔Word, PDF↔JPG. For anyone whose daily workflow mixes images and PDFs — most office workers, students, accountants, legal — having both in one tab is worth more than 10% tighter image compression.
• AI image tools bundled — they don't ship any. Background removal ( /remove-background) and 2×/4× upscaling ( /upscale-image) — free, unlimited, running fully in your browser via ONNX. remove.bg alone charges $9–$99/mo for background removal; we include it because compute on-device costs us nothing. TinyPNG is pure compression; we're compression + AI image toolkit for the same price.
• Audio, video, data — beyond images entirely. MP3, WAV, FLAC, AAC, MP4, MOV, WebM, GIF, CSV, JSON, XML, YAML. If your file workflow spans media types, a single-purpose image compressor solves one corner; we solve the whole corner plus adjacent ones.

Pricing — side-by-side

Tiers verified on both public pricing pages as of 2026-04-24. TinyPNG's numbers have been stable for several years; ours are current to this revision.

The honest math: if you compress fewer than 20 images a month and never need PDFs or AI, TinyPNG is free and you should probably keep using it. If you compress more than that — or want the rest of the toolkit at the same price point — our free tier gives you 75× more headroom, and our paid tier is about half the cost with no per-image meter.

Which should you use when?

We don't need to be the only image compressor in your bookmarks. Here's the honest rule:

1. Use TinyPNG for a few high-value hero images per month. If you have 20 or fewer PNGs or JPGs a month that need to be as small as physically possible — a hero banner, a bandwidth-sensitive product shot, an OG image for a blog post — TinyPNG's proprietary algorithm often wins on byte count at matched quality. For that narrow job it's the right tool, it's free for that volume, and we won't pretend otherwise.
2. Switch to FireConvertApp the moment the volume, format, or job type grows. More than 20 images a month? Hit our /compress-jpeg — 50/day free. iPhone HEIC dump? TinyPNG doesn't decode HEIC; try /heic-to-jpg. PDFs mixed into the workflow? They don't do PDFs; we have /merge-pdf and /compress-pdf. Need background removal or upscaling? /remove-background and /upscale-image are free and unlimited.
3. Use the API when you automate. Our /api/v1 covers image convert + PDF ops with Bearer auth and flat-rate pricing. Their API is more mature and has more client libraries, but costs $0.09/call after 500 free per month. For new pipelines that will run thousands of calls a month, flat-rate often wins on total cost. For pipelines already wired to TinyPNG and working, there's no forcing reason to switch.

The real comparison isn't “which compresses better” — it's “which fits the size and shape of your workflow.” TinyPNG is purpose-built for low-volume high-quality per-image compression. We're built for the daily file-handling workflow that mixes images, PDFs, AI tools, and occasional conversions. Both honest, both useful, different jobs.

Common questions

Is TinyPNG's compression actually better than yours?

On many images, yes — measurably. TinyPNG has spent over a decade tuning a proprietary smart-lossy algorithm that's specifically designed to discard perceptually-invisible detail in PNG and JPG files. On a photographic PNG with lots of similar colors, their output is often 10–20% smaller than what MozJPEG or OxiPNG produces at matched SSIM. That's legitimate engineering, not marketing. We use solid open-source encoders (MozJPEG + OxiPNG + libwebp) with sensible defaults. For 95% of use cases the difference is small and the file is still much smaller than the original; for bandwidth-critical hero images where every byte matters, TinyPNG often wins on pure compression ratio. We don't pretend otherwise.

Then why not just use TinyPNG?

Because their free tier caps at 20 images per month with a 5 MB per-file limit. If you compress more than that — product photos for a Shopify store, a folder of scanned documents, an iPhone photo dump, screenshots for a weekly blog — you hit a paywall fast. Their paid tier is $25/month for 500 images, $0.05 per image after that. For many users the honest math is: TinyPNG is better per-image but you can only use it 20 times a month for free. We give 50 compressions per day free, plus PDF tools, AI background removal, and HEIC/TIFF/BMP support for the same $0.

What's TinyPNG's exact pricing as of 2026?

Free: 20 images/month, max 5 MB each. Developer API: 500 calls/month free, then $0.09 per call. Pro subscription: $25/month for 500 images with cloud features (resize, WebP convert, S3 upload), $0.05 per image overage. One-time Photoshop plugin: $99. All figures from their public pricing page, verified April 2026 — they've been stable on these numbers for several years. Our flat-rate Basic at $12.99/month is roughly half their Pro price and doesn't meter per-image.

Do you support PNG transparency and JPG color profiles like TinyPNG?

Yes. PNG alpha channel is preserved by default across /compress-jpeg, /convert-image, and the conversion matrix. JPG EXIF, ICC color profiles, and orientation tags are preserved when you toggle "Keep metadata" (on by default for conversions, off by default for compression to squeeze more bytes). If you need to strip metadata for privacy, the same toggle handles it. TinyPNG does this well too — it's a wash on metadata handling.

Can I use an API like TinyPNG's?

Yes — our v1 API covers image convert + PDF merge/split/compress/to-jpg at /api/docs, with Bearer auth and flat-rate monthly pricing. TinyPNG's API is more mature (14 years of production use, battle-tested client libraries in half a dozen languages, integrated with WordPress and Shopify plugins). For a brand-new CI pipeline we're competitive and cheaper at scale; for an existing production WordPress/Shopify stack already wired to TinyPNG, switching is work you might not need. We'll say this plainly: their API maturity is a real advantage, especially if you're already using it.

Will my compressed files look different between the two tools?

On most web-destined images, no visible difference at equivalent quality settings. Open both outputs in a pixel-perfect zoomer and you can sometimes spot where TinyPNG preserved slightly more detail in a gradient or slightly smoother compression artifacts in a photo. For 99% of use cases — thumbnails, product shots, blog inline images — the output is visually indistinguishable. Where TinyPNG wins is the byte count at matched quality, not the look. If your use case is "make this look good at small size," both tools get you there.
