Compress PDF

Pick a level, drop in a PDF. We downsample and re-encode images to the level you choose, recompress every stream, and strip non-essential metadata. Text, vectors, signatures, and form fields are preserved.

Balanced — strong savings, crisp on screen. Recommended for most PDFs.

How to

  1. 01

    Choose a compression level

    Low keeps the most image detail; High makes the smallest file. The bigger the images and scans in your PDF, the more each level shrinks it.

  2. 02

    Drop in your PDF

    Upload the file you want to compress. Images are downsampled to the level's target resolution and re-encoded; text and vectors are untouched.

  3. 03

    Download the smaller file

    Get your compressed PDF back in seconds. Signatures and form fields stay intact.

Why Pditor

Smaller, still sharp

Three levels let you trade size against fidelity, so you can hit an email limit without turning text fuzzy.

Forms and signatures survive

Compression preserves form fields and existing signatures instead of flattening them away.

FAQ

How much smaller will my PDF get?+

It depends on the file. Scanned and image-heavy PDFs shrink the most; text-only PDFs that are already optimised may change little.

Will compressing reduce text quality?+

No. Text and vectors stay sharp at every level — only images are downsampled. Higher levels lower the image resolution more, which is where the size savings come from.

Does compression remove my signatures?+

No. Signatures and form fields are preserved.

How long are my files kept?+

Inputs and the compressed output are deleted within an hour on Free, up to 24 hours on Pro.
