Which target size should you pick?
- Under 1MB — the standard for job portals, visa forms and most uploads.

Frequently asked questions
Why is my PDF file so large?
Scanned pages are saved as images at high resolution. A single scanned page at 300 DPI can be 1–2MB. Compression reduces image quality just enough that the file shrinks dramatically while staying perfectly readable.
Will compressing my PDF reduce quality?
For text documents, barely noticeable. The compressor keeps text sharp while cutting file size. For PDFs with photos there is a trade-off — but for forms, CVs and certificates the result looks identical.
Is the PDF compressor private?
Yes. Compression happens entirely in your browser using JavaScript. Your documents never leave your device — important for CVs, ID cards and certificates.
What target size should I choose?
Under 1MB for job portals and visa forms. Under 500KB for email attachments. Under 200KB/100KB for government portals with strict limits.
