Re-renders pages at a lower quality to shrink file size
Pages are re-rendered as images to shrink size, so text stops being selectable in the result — best for scanned or image-heavy PDFs.

About the Compress PDF
Email providers and upload forms often refuse attachments over 10 or 20 MB, and scanned PDFs pass that limit quickly. This compressor redraws every page as a JPEG image at the quality level you pick, which strips heavy embedded images, fonts and other data. It works well for scans and photo-heavy files, and everything happens inside your browser.
What you can do
- Pick one of three levels: Smallest file, Balanced or Best quality.
- Compare the original size, shown when you load the file, with the size of the compressed result before downloading.
- Try another level on the same file if the first result is too large or too soft.
- Pages keep their original dimensions, so the compressed copy prints at the same paper size as before.
When it works best
- Scanned documents and phone captures that are much larger than they need to be.
- Brochures or portfolios full of high-resolution photos that need to fit an email limit.
- Upload portals for visa, job or university applications with a strict file size cap.
- Shrinking a set of photographed receipts or homework pages before uploading them to a portal.
Things to know
- Each page becomes an image, so text in the compressed file can no longer be selected, searched or copied, and links and form fields are lost.
- A PDF that is mostly plain text may get bigger rather than smaller; compare the sizes and keep the original if so.
- Smallest file can make small print blurry. Check the result before sending, and use Best quality for documents with fine detail.
- To make the compressed file searchable again, run it through PDF OCR. The compression itself never leaves your device.
- Fonts and vector graphics are flattened into the page image, so zooming far in shows pixels rather than crisp edges.
Frequently asked questions
Each page is redrawn as a JPEG at the level you choose, which discards heavy embedded images, fonts and other data.
No. Pages become images, so text, links and form fields stop working. Run the result through PDF OCR if it needs to be searchable.
Smallest file for the biggest saving, Balanced for everyday use, and Best quality for pages with small print or fine detail.
Text-only PDFs are already compact, and turning them into images can add size. Compare both sizes and keep the original in that case.
No, compression runs entirely in your browser.
