Frequently asked questions

Can all PDFs be compressed to 1 MB?

All PDFs can be reduced in size, but extremely large or image-heavy files may not always reach exactly 1 MB, even at the highest compression level. For most documents the result is very close to the target, and the compressed version looks identical to the original. You can try a higher level if needed.

Is my data secure when compressing PDFs?

Yes. Your files are processed securely and deleted automatically after the compression is complete.

Can I compress the same PDF multiple times?

Yes. If the first compression level does not bring the file close enough to 1 MB, upload the result and try a higher level. Each round of compression brings the file size down further. For most documents one pass is sufficient, but a second round can help with particularly large files.
