About Compress PDF
Compress PDF reduces the size of heavy PDFs so they fit email limits and upload forms. Choose a preset: light compression for the best quality, balanced for everyday documents, or high compression when the file size matters most. A before-and-after size comparison shows how much was saved.
This tool works by re-rendering each page as an optimized image and rebuilding the PDF. That is very effective for scanned documents and image-heavy files, but it means the text in the result is no longer selectable or searchable. If you need to keep selectable text, use the light setting or keep the original as well.
Common ways to use it
- Shrink a scanned application or ID document to meet a portal's upload limit.
- Make a photo-heavy brochure small enough to send by email.
- Reduce a large presentation export before sharing it in a chat.
Compress PDF FAQ
Will the text still be selectable after compressing?
No. Pages are converted to images, so the text becomes part of the picture. Keep your original file if you need searchable text.
What if the compressed file is not smaller?
Some PDFs are already well optimized. The tool shows the before and after sizes so you can see this, and you can try a stronger preset or keep the original.
Is my document uploaded?
No. Compression runs entirely inside your browser, so the file never leaves your device.
