How small should the file get?
Without a target size, ReduPDF compresses in a balanced way. With a target size, it automatically compresses as much as needed to stay under it.
Limits the longest edge of the photo in pixels — independent of the target size.

Only needed if you want to set a specific image quality instead of a target size.

Frequently asked questions
Is ReduPDF really free?
Yes. You can shrink as many PDFs and photos as you like, free of charge, with no account and no watermark.
Are my files uploaded anywhere?
No. Compression runs entirely in your browser. Your file never leaves your device and is never stored anywhere.
Does the text in the PDF stay searchable?
Yes, as long as only the embedded images are compressed. Pages are only rebuilt as images if a very small target size requires it — in that case the text is no longer searchable.
How small can I shrink my PDF for a government portal?
Pick, for example, the under 10 MB option in the target size field for typical application portals — ReduPDF automatically compresses as much as needed to stay under it.
