Make a large PDF smaller. Pages are saved as pictures, so scans shrink the most.
Compress PDF makes a PDF smaller so it fits an email or an upload limit. Everything runs in your browser, so your PDF is never uploaded.
It works by drawing every page as a picture at a lower quality and building a new PDF from those pictures. This shrinks scanned documents and photo-heavy files a lot.
Add your PDF, then choose how to compress it. Pick a quality level (Light, Balanced or Strong), or choose Target size and select a limit such as 200 KB or 1 MB, or type your own number in KB or MB. Press Compress PDF, check the preview and the new size, and download. If the result is not smaller, you keep your original.
Because pages become pictures, the text in the compressed file can no longer be selected or searched. Keep your original if you need that.
Scanned documents and files full of photographs shrink the most. PDFs that are mostly text can come out larger, and in that case the tool tells you so.
Strong gives the smallest file with visible softness; Light keeps pages sharper with a smaller saving.
When you choose a target size, the tool tries the sharpest setting first and only softens the pages as far as it has to, so you get the best-looking file that fits your limit.
Add it to the tool, pick a level and press Compress PDF. Scanned PDFs often become several times smaller.
Yes. Choose Target size, select 100 KB, 200 KB, 500 KB, 1 MB, 2 MB or 5 MB, or pick Custom and type your own size in KB or MB. The tool aims for the sharpest file at or under that size.
Then the tool gives you the smallest file it could make and tells you its size, so you can decide whether to use it or try a larger limit. Very small limits on a PDF with many pages are usually not possible.
No. The pages are saved as pictures, so text is no longer selectable. Keep the original if you need searchable text.
A PDF made of real text and vector graphics can be smaller than pictures of its pages. The tool then keeps your original instead of a bigger file.
No. The compression runs in your browser.
Balanced suits most files. Choose Strong when you must hit a small size and can accept softer pages.
