Need to submit a PDF under 1 MB? Choose Balanced and enter 1 as the upload limit.

Compare the original and compressed sizes. If the result is still too large, try Strong and check that the images are clear enough.

What to know before using PDF Compressor

Start with Balanced for most PDFs. Strong can make images less sharp, while selectable text stays selectable. PDFs with large JPEG images usually have more room to shrink. Text-only files or PDFs that are already optimized may stay close to their original size. Files stay on your device. Use an unsigned, unencrypted PDF up to 50 MB.
