Frequently asked questions
How much smaller will my PDF get?
It depends on the file. PDFs full of photos or scans often shrink by 50-90%, while a text-only PDF is already small and may barely change.
What do DPI and image quality do?
DPI sets how many pixels each image keeps per inch of the page — 144 is plenty for screens, 300 for printing. Image quality is the JPEG quality used when re-encoding; lower values save more space but soften details.
Will my text stay selectable?
Yes. By default only images are recompressed, so text, fonts and vector graphics stay exactly as they were. Text only becomes pixels if you enable 'Flatten pages to images'.
Is my file uploaded to a server?
No, compression runs entirely in your browser and your file never leaves your device.
Can I compress several PDFs at once?
Yes, add as many files as you like — each is compressed with the same settings and you can download them individually or all together as a ZIP.
