FireConvertApp vs Smallpdf: honest head-to-head

Feature-by-feature matrix

18 rows. We don't win all of them. Orange check = meaningful advantage. Grey = roughly equivalent.

Where Smallpdf beats us

Being honest beats being defensive. If any of these are must-haves for your workflow, Smallpdf Pro is the better fit.

• Full PDF editor. Smallpdf has an in-browser editor for text, annotations, and image placement. We don't — our PDF path is convert/compress/merge/split, not authoring. If you're doing heavy PDF editing, stay there.
• OCR accuracy and coverage. Scanned PDFs → searchable PDFs with language auto-detect. One of the better OCR implementations in the PDF SaaS space. On our roadmap but not shipped.
• Qualified e-signatures. PKI-backed signing with audit trail is a Pro feature there. Not on our roadmap; if signing is critical, stay on Smallpdf or use a dedicated e-sign tool.
• PDF-to-Office fidelity. They license Solid Documents' conversion engine — the gold standard for preserving tables, columns, and embedded images when round-tripping PDF ↔ Word / Excel / PowerPoint. Our v1 path is text-first.
• Desktop apps + Chrome extension. Native Windows/macOS apps for offline use, Chrome extension for one-click right-click conversions. We're web-only.

Where we beat Smallpdf

• A free tier that lets you work. 50 conversions per day vs Smallpdf's 2 tasks per day — that's 25× the headroom. No hourly throttle on our free tier, no hard-block paywall, no aggressive sign-up prompt after the first task.
• Honest compression. When our wrapper-compress can't save at least 1% on your file, we return your original with a notice and point you at the deep-compress opt-in. Smallpdf returns a “compressed” file either way, even when it's the same size. Trust-building over dark patterns.
• AI bundled — they don't ship it at all. Background removal ( /remove-background) and 2×/4× image upscaling ( /upscale-image) — free, unlimited, no upload. remove.bg charges $9-99/mo for just background removal; we give it away because it runs on your device. Smallpdf doesn't have either tool.
• Batch mode, free. Drop a folder of PDFs or images, get a ZIP back. Free on our side, Pro-gated on theirs. If you're regularly processing more than one file at a time, batch alone is the switch.
• Image conversion breadth. 60+ image tools including HEIC ↔ JPG/PNG (iPhone photos), WebP / AVIF / TIFF / JFIF / BMP conversions, ICO favicons, presets for Instagram / YouTube / print. Smallpdf handles the PDF-adjacent image bits only.
• Privacy we can prove. Our AI image tools run 100% in-browser — open DevTools → Network during inference and watch: zero outbound requests. Server-side conversions process in memory and auto-delete within the hour. Smallpdf uploads everything per standard cloud-SaaS behaviour.
• Public API in every tier. Bearer-authed, rate-limited /api/v1 with 5 live endpoints. Smallpdf API is Pro-only; ours is included in Free (rate-limited) and all paid tiers.

Coming from Smallpdf? The 3-minute switch

1. Open the tool you use most there. Most likely: Compress, Merge, or Convert PDF. Our matching tools are at /pdf-compressor, /pdf-merge, and /convert/pdf-docs.
2. Drop the file + download. No sign-up for anonymous use. Same UX shape as Smallpdf — just without the 2-task counter counting down in the corner.
3. Try the tools they don't ship. While you're here: run an image through /remove-background (runs in your browser, no upload) and /upscale-image — both are free, both would be $9-$99/month extra subscriptions elsewhere.

If you're a heavy editor/OCR user, the honest answer is to stay on Smallpdf Pro for those specific workflows and use us for everyday compress/merge/split/convert. Many teams run both.

Common questions

Why does Smallpdf only let me do 2 tasks per day for free?

That's their freemium wall — generous enough to demo the tool, restrictive enough to push you onto Pro ($12/user/mo). FireConvertApp takes the opposite approach: 50 conversions per day on free (25× more), and the AI image tools have no cap at all because they run in your browser. We make money on file-size caps and API volume, not on blocking basic use.

Is FireConvertApp compression as good as Smallpdf's?

The default wrapper-compress path is equivalent — both re-save with object streams, subset fonts, and strip unused metadata. Where we differ: we tell you when the result isn't actually smaller than the input (common on image-heavy PDFs) and return your original instead of handing back a same-sized file labelled "compressed". For real image-heavy savings, enable our "Re-encode images" option — typical 60-90% shrinkage on scan-heavy PDFs.

Can I e-sign, edit, or OCR PDFs on FireConvertApp?

Not yet. OCR is on the 90-day roadmap. Editing and e-signatures aren't on our near-term roadmap. If you need any of those today, Smallpdf Pro is a reasonable fit. For everything else — compress, merge, split, convert, PDF↔Word/EPUB — you get unlimited daily use and the AI image tools on top.

Are my PDFs uploaded to your servers?

The PDF tools run server-side (sharp, pdf-lib, pdfjs) — files arrive, get processed in memory, stream back. We retain nothing beyond a temporary working buffer, auto-deleted within the hour. The AI image tools (/remove-background, /upscale-image) run 100% in your browser; those files never leave your device. Open DevTools → Network during inference and watch — zero requests.

What about batch processing?

Free on our side — drop a folder of files into most tools and get a ZIP back. Smallpdf batch requires Pro. For power users hitting "2 tasks per day" hourly on Smallpdf, batch alone is usually enough reason to switch.

Why would I stay on Smallpdf?

Four reasons, all legitimate: (1) you need OCR, e-signatures, or the PDF editor today; (2) you live inside the desktop apps or Chrome extension; (3) you need best-in-class PDF-to-Office fidelity (they license Solid Documents); (4) your team is already on Pro and the switching cost outweighs ~$144/year saved. For everyone else — students, freelancers, people hitting the 2-per-day wall on personal files — we're the better fit.
