How to use it
- Pick a preset, or set Max KB in Settings.
- Drop your images.
- Download each PDF, or all as a ZIP.
How the conversion works
Each image is placed on a PDF page of the same shape. JPG data is embedded directly, so there is no second round of compression and the page looks exactly like the image.
Questions
What page size does the PDF use?
The page matches the image shape, sized at 150 DPI. For an A4 page, resize to A4 first using the A4 page with format set to PDF.
Is my photo uploaded to a server?
No. The resizing runs inside your browser with JavaScript, so the image never leaves your device. Once the page has loaded, resizing keeps working even if you go offline.
