Compress PDF to a Target Size
Pick a size, add your PDF and CometBits reduces it to fit. It works by turning each page into a compressed picture, which gives a much smaller file but means the text is no longer selectable. That is usually fine for forms and uploads. Your file never leaves your device.

Tips and common mistakes
Choose a target that matches the form
Most government and college portals say a maximum size, such as 100 KB, 200 KB or 500 KB. Pick the size from the form, not a smaller one, because a lower target means a blurrier page. Aim a little under the limit (for example 190 KB for a 200 KB limit) so the portal does not reject it by a few bytes.
Start from the original, not a copy that was already compressed
Every time a PDF is compressed again, quality drops further. If you still have the original scan or document, use that. Scans of paper documents shrink the most. A PDF that is mostly text and already small may not shrink much.
Check the result before you upload
Open the compressed file and zoom in on the smallest text, stamps and signatures. If they are hard to read, raise the target a little. Remember that this method turns each page into a compressed picture, so you can no longer select or search the text.

Questions
Will the text still be selectable?
No. To reach small sizes, each page is converted to a compressed image. This works well for forms, scans and uploads, but if you need searchable text, keep the original too.
What if my PDF can not reach the target?
Very long PDFs or tiny targets can make pages blurry. We pick the best quality that fits and warn you if the result looks too soft. Try a larger target or split the file.
How long does it take?
Most PDFs take a few seconds. A scan of 30 or more pages can take up to a minute on an older phone. The progress bar shows how far along it is.
Is my document uploaded?
No. All of the work is done by your browser on your own device.
