Will compressing a PDF lose quality?

Squish Files compresses PDFs by re-rendering each page as an image at a lower resolution. The Screen and eBook settings noticeably reduce quality in exchange for smaller file sizes, while Print and High settings preserve more detail. Text in the compressed PDF will not be selectable.

Will compressing a PDF affect text quality?

Squish Files compresses PDFs by re-rendering each page as an image. This means text won't be selectable in the output. The Screen and eBook levels reduce visual quality more aggressively in exchange for smaller file sizes, while Print and High settings look much closer to the original.

Can I convert images to PDF?

Yes — use the Images → PDF tab. Drop in any number of JPG, PNG, or WebP images, reorder them with the arrows, and click Create PDF to bundle them into a single PDF file.

How do I extract pages from a PDF as images?

Use the PDF → Images tab. Drop your PDF in, choose your output format (JPEG or PNG) and resolution (72–300 dpi), then click Extract Images. Each page becomes a separate image file, all downloaded together as a ZIP.
