FAQ
Why did my PDF barely get smaller?
Standard keeps the content as is and only tidies the file structure, so PDFs that are already well optimized shrink very little. If the file doesn’t shrink by more than 1%, we suggest keeping the original instead of downloading. For scans or image-heavy PDFs, click Try strong compression.
What’s the difference between Standard and Strong?
Standard doesn’t touch text or images, so there’s no quality loss. Strong redraws every page as a JPG and builds a new PDF, which shrinks the file much more but can look softer than the original. Page sizes stay the same.
Can I still select or search text after strong compression?
No. Each page becomes a single image, so text can’t be selected or searched, and links stop working. Use Standard for documents where you need searchable text.
Should I pick Medium (150 DPI) or Small (100 DPI)?
Medium (150 DPI) works well for reading on screen and printing. Use Small (100 DPI) when you need to get under an email attachment limit. Small text can be hard to read at 100 DPI, so open the result to check.
A text-only PDF got bigger with strong compression.
Text-based PDFs are already small, and turning pages into images can make them larger. In that case you won’t get a download, just a note to keep the original.
How large a PDF can I compress?
Each file can be up to 100 MB. Strong compression renders every page in turn, so long documents take a while, especially on phones.
