COMPRESS PDF GUIDE
Reduce PDF file size before email or upload
Large PDFs can be difficult to email or may exceed an upload form’s limit. Start with recommended compression, then check the downloaded PDF’s size and readability before you submit it.
Choose the right approach
- Use Light when preserving the original appearance matters most.
- Start with Recommended for everyday sharing.
- Try Strong when the result still needs to be smaller.
Important: check the result
File-size reduction depends on the original PDF. This tool does not promise a specific target such as 1MB or 5MB. Open the result and zoom in on small text, signatures, and scanned pages before sending it.
Frequently asked questions
Can I compress a PDF to a fixed size?
Every PDF is different, so a fixed output size cannot be guaranteed. Try the available levels and check the downloaded file size.
Should I compress the result again?
For the best quality, retry from the original PDF rather than repeatedly processing an already compressed file.

PRACTICAL PDF SIZE GUIDE
Check these limits before reducing a PDF file size
PDF upload limits vary, often 1MB, 5MB, or 10MB. Check the destination rule first, then review both the downloaded file size and the readability of small text, stamps, tables, and scans.
Under 5MB
A common limit for general portals and email attachments. Start by comparing recommended compression.
Under 10MB
Often used for scanned or photo-heavy submissions. Readability checks are especially important.
A quick check before submitting
- Check the destination’s maximum size and PDF-format requirements.
- Keep the original PDF and start with recommended compression.
- Confirm that the downloaded result is below the stated limit.
- Open the first, middle, and last page and zoom in on text, stamps, tables, and photos.
- If it is still rejected, also check password protection, page limits, and total attachment limits.
Frequently asked questions
Can I make a PDF exactly 1MB or 5MB?
Reduction varies with the PDF structure and included images, so an exact output size cannot be guaranteed. Check the actual downloaded size.
Why does my PDF barely get smaller?
Already optimized or text-heavy PDFs can have little removable data.
Does compression change my original PDF?
No. Compression creates a separate new PDF and keeps the original file unchanged.

Frequently asked questions
Will it make the PDF exactly 10MB?
PDF contents vary, so the tool works toward a result below 10MB. Check the downloaded file size.
What if it is below 10MB but still will not upload?
Also check the file type, page limit, and total-attachment rules on the destination site.
