Compress PDF with Image-Based Output

0 filesFiles are processed in this browser. Supporting libraries, workers and optional OCR models load from third-party CDNs. Files must be non-empty and no larger than 50 MB. Keep the original: editing can invalidate digital signatures, and rebuilding pages may not preserve forms, bookmarks or document metadata.
Lossy scan-style compression: Every page becomes a JPEG image. This removes selectable text, links, forms and existing digital signatures, and may increase the file size for text-only PDFs. Keep the original; choose a lower compression level for fine print.
When to use Compress PDF with Image-Based Output
Create a scan-style copy of an image-heavy PDF for sharing. This tool renders each page to a JPEG image, so it changes the document rather than preserving the original text layer.
How to use this PDF tool
- Add one or more PDFs up to 50 MB each, within the page’s batch limit.
- Choose a compression level and optional grayscale based on the detail you need to keep.
- Compress the documents and compare the resulting size with the original.
- Inspect small text and illustrations, then download a result or the batch ZIP.
A practical example
For scanned receipts, try a moderate setting and inspect the smallest amounts and dates. A text-only report can become larger after rasterization, so compare the actual files rather than expecting a fixed percentage saving.
Output and document limits
Output pages are JPEG images. Selectable text, links, forms and existing digital signatures are lost. Lower quality or resolution can blur fine print. File size reduction is not guaranteed, and the output may be larger.
Frequently asked questions
Is this lossless PDF compression?
No. It creates JPEG-based page images and can reduce visual quality. Keep the original when text selection or document features matter.
Why did my PDF become larger?
A compact text or vector PDF can expand when every page becomes a picture. Compare sizes and use the original if the result does not help.
