PDF Compressor makes PDFs smaller by recompressing the photos and scans inside them. Smart mode lowers each image to the chosen resolution at the size it appears on the page and saves it as JPEG, while text, vector graphics, links, bookmarks, and forms stay as they are.
Strong mode turns every page into a JPEG image, which gives the smallest files for scanned documents but makes text unsearchable and removes links and forms. If a result is not smaller than the original, the original is kept. Everything runs in your browser.
Are my PDFs uploaded?
No. Files are read and compressed in your browser, and they are gone when you close the page.
Why did my PDF barely get smaller?
Smart mode only recompresses images. PDFs that are mostly text, or that already use small images, have little to remove. Images in CMYK, JPEG 2000, JBIG2, or other special formats are left unchanged.
What are the limits?
Up to 20 PDFs, each up to 100 MB. Encrypted or password-protected PDFs cannot be compressed.
Will text still be selectable?
Yes in Smart mode. Strong mode turns each page into an image, so text can no longer be selected or searched.
