Frequently Asked Questions

Is there a file size limit for uploads?

Yes. Most portals accept PDFs up to 5MB, 10MB, or 25MB depending on the platform. Check the specific portal requirements before compressing — use the smallest target that the portal allows for best quality.

What happens if my compressed PDF is still too large?

Try compressing to a smaller target size. If the portal requires under 200KB, use our Compress PDF to 200KB tool. For very strict limits like 50KB, use our Compress PDF to 50KB tool.

Will my PDF look different after compression?

For text-heavy PDFs, no visible difference. For scanned documents or image-heavy PDFs, some quality reduction is expected. Always preview the output before uploading.
