Frequently asked questions

Short, direct answers about how Convertoza works — privacy, supported formats, limits, and accounts.

Showing 20 of 20 questions

Where are my files uploaded to?
Nowhere. Every conversion happens inside your browser tab using client-side JavaScript. Your files never leave your device.

General

Is there a file size limit?
There is no hard server-side limit because files never leave your browser. Very large files may be slow depending on your device memory.

General

Why isn't DOCX to PDF pixel-perfect?
DOCX to PDF is a text-first conversion using Helvetica. Layout, fonts, images, and tables are not preserved — this is by design for a browser-only, no-upload conversion.

General

Can I convert scanned PDFs?
Scanned PDFs require OCR. Use the dedicated OCR tool at /ocr which runs locally in your browser using Tesseract.js.

General

Do you support batch conversion?
Yes — batch conversion is available on the homepage converter for supported formats.

General

Is Convertoza open source?
The converter engine is a thin wrapper around open libraries: pdf.js, pdf-lib, Mammoth, SheetJS, and jsPDF.

General

Does Convertoza upload my files to a server?
No. Every conversion runs entirely inside your browser using WebAssembly and standard browser APIs. Files never touch our servers.

Privacy

Do you track the contents of my files?
No. We don't inspect, log, or store file contents. Only anonymous page-view counts are collected.

Privacy

Which image formats are supported?
PNG, JPG, WebP, BMP, GIF, SVG and ICO — convert between any pair, without signing in.

Formats

Can I convert PDF to Word (DOCX)?
Not yet. PDF → TXT and PDF → PNG are supported today. True PDF → DOCX requires layout reflow that isn't reliable in-browser.

Formats

Do you support HEIC or RAW images?
Not currently. HEIC and camera RAW formats require heavier decoders. Convert them to JPG on your device first, then use Convertoza.

Formats

How many files can I convert per day?
Verified accounts get 20 conversions per 24 hours. Anonymous users get 3. Image conversions don't require sign-in.

Limits

Is there a file-size limit?
No hard cap, but files above ~200 MB may be slow because your browser holds them in memory during conversion.

Limits

Can I convert multiple files at once?
Yes — use the Batch converter on the home page. Pick a target format per file and download individually or as a ZIP.

Limits

Do I need an account?
Only for non-image formats (PDF, DOCX, spreadsheets). Image conversion works without an account.

Account

How do I reset my password?
Visit /auth, switch to the Login tab, and use 'Forgot password'. A reset link is emailed to you.

Account

Can I delete my account?
Yes. Sign in, open Profile, scroll to the Danger zone, and confirm deletion. This removes your profile and conversion history.

Account

Which browsers are supported?
Any modern browser: Chrome, Edge, Firefox, Safari, and their mobile equivalents from the last two years.

Technical

Does Convertoza work offline?
Once loaded, most conversions continue to work offline because they run locally. The initial page load requires a network connection.

Technical

Is the code open source?
The converter engine is a thin wrapper around open-source libraries: pdf.js, pdf-lib, Mammoth, SheetJS, jsPDF, and fflate.
