Compress a PDF to 500KB
Shrink a PDF to roughly 500KB. Set your target and Squishly's deep engine searches for the setting that fits — text stays selectable, and every result comes with a Proof of Fidelity report.
Strongest compression, and it keeps any existing text selectable and searchable. Note: a scanned or image-only PDF has no text layer, so it stays image-only (that needs OCR).

Frequently asked questions
- How does the target size work?
- The deep engine steps image quality and resolution down until the PDF lands near your target — here about 500KB.
- Will a 500KB PDF still be readable?
- Text stays selectable — only images are compressed. Very small targets soften scanned pages, so pick a larger target if the result looks rough.
- What happens to my PDF?
- It's sent to our server to compress, processed in a private temporary folder that's deleted the moment your download is ready — nothing is stored.
