Frequently asked questions
How do I make a PDF small enough to email?
Most email services cap attachments at around 25 MB, and many job or government portals ask for far less. Start with the Balanced level, check the new size shown after compressing, and switch to Strong if you still need to go smaller.
Why is my text no longer selectable after compressing?
To achieve a large size reduction in the browser, each page is re-rendered as a high-quality image. That is what removes the bulk, but it also means the text becomes part of the picture. If you need the text to stay searchable, keep the original file for your records.
Which PDFs shrink the most?
Scanned documents and photo-heavy files shrink dramatically, often by 70% or more. A PDF that is mostly plain text is already small and efficient, so it may barely shrink at all — and could even grow slightly.
Why can I no longer select the text afterwards?
Compression works by rebuilding each page as an image, which is what makes large reductions possible — but it means the text becomes part of the picture rather than something you can highlight, copy or search. If you need the text to stay selectable, send the original instead and split it into smaller parts.
Is there a file size limit?
There is no limit imposed by us, only by your device memory. Very large documents with hundreds of pages will take longer and work best on a desktop computer.
