About this tool
JPG to PDF builds one PDF from photos and screenshots you already have. Drag them into reading order. Reducing file size is on by default so a phone photo does not become an enormous page. Pictures are not uploaded to a converter. PNG and WebP can sit in the same packet when the browser can decode them. HEIC depends on that same browser support; no HEIC library is bundled.
JPG to PDF stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: photos become pages here, without a conversion service.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
