Frequently Asked Questions
Why didn't my PDF get much smaller?
This tool compresses by re-rendering pages as images, so text-based PDFs with little to no images may already be compact and won't shrink significantly — try a lower quality setting if you need a smaller file regardless.
Will the text still be selectable after compressing?
No, since each page is converted into a compressed image, the output PDF will look the same but the text will no longer be selectable or searchable — use this tool primarily for scanned documents or photo-heavy files.
What resolution should I choose?
Medium works well for most sharing and emailing needs; choose Low only if file size is critical and some blurriness is acceptable, or High if the PDF will still be read on a large screen or printed.
