Practical tips
Pages become images
This tool rebuilds each page as a JPEG image, so text will no longer be selectable or searchable.
Use for scan-heavy files
It suits scanned documents where text is already part of the image and file size is the main problem.
Keep text searchable with Compress
If selectable text matters, use Compress PDF instead, which keeps the text layer.
Frequently Asked Questions
How is this different from standard compression?▼
Unlike standard compression, this tool rasterizes each page into a JPEG image and rebuilds the PDF from those images — it doesn't re-encode individual embedded images in place.
Does text quality degrade?▼
Yes. Every page, including any text, is converted into a flattened image, so text is no longer selectable or searchable afterward. Avoid this tool for text-based documents — use Compress PDF instead.
Is the image optimization tool free?▼
Yes, it is completely free to use without registration or installation.
Are files stored on your server?▼
No. All processing occurs locally in your browser to ensure complete privacy.
Is the output quality maintained?▼
Visually similar at normal zoom, but each page becomes a single image — text is no longer selectable or searchable, and fine detail may soften at higher compression levels. Best suited for scanned or image-heavy PDFs.
