Frequently asked questions
- Can I compress a PDF to a specific file size?
- Yes — use target mode to aim for about 500 KB, 1 MB, 2 MB, or 5 MB. The result is approximate: already-optimized PDFs or image-heavy scans may not reach the exact size. Need to compress a PDF to about 1 MB? Try the dedicated 1 MB compression tool linked under Related tools.
- Will compression reduce quality?
- Results vary by content. Text-heavy files often shrink with little visible change; image-heavy scans may trade some detail for size. Check the download if quality is critical.
- How much smaller will my PDF get?
- It depends on the source. Already-optimized PDFs may shrink only a little; large scans often shrink more.
- Is there a file size limit?
- There is no fixed cloud quota. Very large files are limited by your device’s available memory.
- Can I compress on a phone?
- Yes, though large files usually finish faster on a desktop or laptop.
- Do I need an account to compress?
- No. Compression is free without registration.
