A Convertio alternative that never uploads your images
Convertio is a well-known online file converter that processes uploads on its own servers — its privacy policy states files are stored in the EU, bound to the uploading user's IP address, and deleted shortly after conversion. convert.pics takes a different architectural approach for the image formats it covers: HEIC, JPG, PNG, WebP, and AVIF are decoded and re-encoded entirely inside your browser, so there's no file to upload, store, or delete in the first place. The comparison below uses only Convertio's own published Terms of Use and privacy policy, checked 31 July 2026 — see the source link on every row.

When the other tool is the better choice
Convertio genuinely wins on breadth: it states more than 25,600 conversions across 300+ file formats, covering documents, video, audio, and archives, not just images. If a DOCX needs to become a PDF or a video needs re-encoding, that's Convertio's job, not ours — we only convert HEIC, JPG, PNG, WebP, and AVIF. Convertio's privacy policy also states files are stored in the EU and bound to the uploading user's IP address, with input files deleted instantly after conversion — a real, stated privacy posture, just a structurally different one from a file that never leaves the device in the first place.
Frequently asked questions
Is Convertio safe to use?
Convertio's privacy policy states files are stored in the EU, bound to the uploading user's IP address, and not shared with third parties for personal data; input and temporary files are deleted instantly after conversion, and output files within 24 hours if not deleted manually. That's a real, stated privacy policy — but it does mean the file is uploaded and processed on Convertio's servers, which is architecturally different from a tool that never receives the file at all.
What is Convertio's file size limit on the free plan?
Its Terms of Use define the free website tier as a maximum of 100 MB per file, a maximum of 2 concurrent conversions, and a maximum of 10 conversion minutes within a 24-hour period. (The upload page itself displays "1 GB maximum file size or Sign Up" — the 100 MB figure is what the Terms of Use specify for free web use.)
How many free conversions does Convertio allow per day?
Convertio's Terms of Use don't cap a specific number of conversions; instead the free web tier is limited by total conversion time — a maximum of 10 conversion minutes within any 24-hour period, alongside the 2-concurrent-conversion and 100 MB per-file limits above.
Does Convertio delete my files after converting?
According to its privacy policy, yes — input and temporary files are deleted instantly after conversion, and output files are deleted instantly if you click the delete button in the web panel, or automatically after 24 hours if you don't.
Is there a Convertio alternative that doesn't upload my files?
convert.pics is one: every conversion (HEIC, JPG, PNG, WebP, AVIF) happens inside your browser using WebAssembly, and no image data is ever sent to a server — the trade-off is a much narrower format list than Convertio's.
Can convert.pics convert PDFs or videos like Convertio?
No. convert.pics only converts between HEIC, JPG, PNG, WebP, and AVIF images. Convertio's stated range — more than 25,600 conversions across 300+ formats, including documents, video, audio, and archives — covers far more than that; for anything outside images, Convertio is the right tool.
