Which image formats are supported?

Supported formats include JPG, JPEG, PNG, WebP, BMP, and GIF.

Can I combine multiple images into a single PDF file?

Yes, you can combine dozens of images into a single structured PDF document.

Can I adjust page margins and orientation (portrait/landscape)?

Yes, you can select standard page sizes (A4, US Letter), orientations, and margin widths.

Does converting degrade image quality?

No, full native resolution is preserved with optional smart compression.

Are my personal images uploaded to any cloud server?

Never. Everything processes 100% inside your browser using client-side JavaScript.

Is it really free, or are there hidden limits?

Completely free with no usage caps. The free tier includes all core features with generous limits (100MB per file, 100 pages per document). An optional PDF Pro plan exists for those who need these limits lifted and ads removed.

Does it work on mobile phones?

Yes, it runs smoothly on Android and iOS browsers. You can also install the site as a PWA on your home screen so it behaves like a regular app — and works offline after installation.

Which file types are supported?

The tool supports standard PDF files of all versions. For conversion tools, JPG, PNG and WebP images and HTML files are supported — with full support for all languages including Arabic and right-to-left scripts.

Do I need internet the whole time?

You need internet to load the page and processing libraries once. After that, processing happens locally on your device. Install the site as a PWA and every tool becomes available fully offline.

How can you guarantee my files aren't uploaded?

The guarantee is technical, not a marketing promise: the tool runs on WebAssembly inside your browser, and you can verify it yourself — open your browser's developer tools (Network tab) during processing and you won't find a single file-upload request. You can even disconnect from the internet after the page loads and the tool keeps working.

Pro tips for the best results

Expert tips to get the best results:

★Use an up-to-date browser (Chrome, Edge, Firefox or Safari) for maximum processing speed and stability.
★When working with very large files, close other memory-hungry apps to give your browser more room for fast processing.
★Always keep a backup of your original file before making changes — the tool never modifies your source file, but good habits protect you from surprises.
★If you use the tool frequently, install the site as an app (PWA) from the install button — then it works even without internet.

Common problems & instant fixes

Solutions to the most common issues:

❓ The page freezes when I select a very large file

Huge files (over 100MB) can exhaust browser memory. Fix: close other tabs, split the file first with the Split PDF tool, or use Chrome which manages memory most efficiently.

❓ I got a 'file corrupted or unreadable' message

The file is probably password-protected or damaged at the source. Try the Unlock tool first if you own the password, or the Repair PDF tool for damaged files, then try again.

❓ The output doesn't look like what I expected

Double-check the settings before processing (output quality, page range, orientation). Every tool shows clear options before running, and you can retry unlimited times until you get the perfect result.

Why professionals choose this tool

Security here isn't a feature bolted on top — it is the architecture itself: no accounts, no usage caps, no data tracking. That's why lawyers, accountants and researchers handling sensitive documents daily rely on it.

How it stacks up against alternatives

The fundamental difference between this tool and most of the internet is like cooking in your own kitchen versus ordering takeout: both feed you, but in the first case you alone know the ingredients and nobody sees your kitchen. Convert JPG, PNG, and WebP photos into clean PDF documents online for free. Customize orientation, margins, and page sizes (A4, Letter). 100% private in browser.

When weighing your options, judge by three criteria: where are your files actually processed? What does each operation cost in time and money? And how many steps stand between you and the result?
