Are my files uploaded to a server?

No. Every tool on this site runs inside your browser. Your file is read from your disk into your own browser's memory, processed there, and written back out. You can confirm this yourself: open your browser's developer tools, switch to the Network tab, and run the tool — you will not see your document being sent anywhere. It also means the tools keep working if you go offline after the page has loaded.

Which image formats are supported?

JPG and PNG are embedded directly at full quality. Other formats your browser can decode, such as WebP, are converted to PNG first.

Will my photos be compressed?

JPG images are embedded exactly as they are, with no re-encoding, so there is no extra quality loss at all.

How do I stop my images being cropped?

Choose a page size and the image is scaled to fit inside it, never cropped or stretched — any leftover space becomes a margin. If you would rather have no border at all, pick Fit to image and each page takes the exact shape of its picture.

3Build the PDFDownload a single document. JPGs are embedded exactly as they are, so there is no second round of compression.

When you would use this

This is how photos of paperwork become something an institution will accept. Phone shots of a passport, an ID card, a utility bill or a signed form usually need to arrive as one PDF rather than six separate images, and the same applies to screenshots being collected into a report or a photographed whiteboard being filed after a meeting.
