Quick answers
Short, straight answers to the most-asked questions about ToPDF and browser scanning.
Is ToPDF really free? (Yes — here’s the whole catch-free answer)ToPDF is completely free: no watermarks, no scan counters, no premium tier, no account. How that’s sustainable is the interesting part.
Does ToPDF add a watermark? No — your PDF contains only your documentNo watermarks, no branded footer pages, no hidden promo metadata. What’s in the file is your pages, nothing else.
What are ToPDF’s limits? Pages, sizes and formats, stated plainlyUp to 20 pages per document, unlimited documents, ~2400 px page rendering, JPG/PNG/HEIC/WebP input — every boundary in one page.
Do I need an account to scan? No — and there’s nothing to sign intoToPDF has no registration, login, or user system at all. Open, scan, download — identity never enters the flow.
Where are my PDFs saved? (ToPDF keeps nothing — here’s where files go)Downloads land in your device’s Downloads folder or wherever Share sends them; ToPDF itself retains zero copies after you leave.
Which photo formats can I scan? JPG, PNG, HEIC, WebP — all handledEvery format phones and screenshots produce works, including iPhone HEIC (converted locally). What each format is and what to do with oddballs.
Does ToPDF work offline? Yes — fully, after one first visitScanning, cropping, naming and PDF export all run without internet once the engine is cached. Airplane-mode paperwork is a real workflow.
Can I put several documents into one PDF? Yes — here’s howMix an ID, a form and a receipt into one file, or keep one-document-one-file discipline: how combining works and when each choice is right.
Scanning landscape documents (certificates, spreadsheets, wide forms)Wide originals are first-class citizens: how orientation handles them, when to rotate, and mixed portrait+landscape PDFs.
Why did my scan open the corner editor instead of finishing?The editor appearing is a feature: when detection isn’t sure, you confirm corners before any crop is applied. What triggers it and how to breeze through.
Can I use ToPDF for business and client documents?Yes — freely, including commercial use. Why on-device scanning is actually a compliance asset when handling client paperwork.
How accurate is the auto-crop? Honest numbers and the safety netMost photos crop perfectly on the first pass; the tricky minority route to a one-tap confirmation instead of failing silently. Here’s the honest picture.
