Compress scanned PDFs with adjustable image quality
This compressor renders the selected PDF pages as JPEG images and rebuilds the document. It can help with large scans and image-heavy PDFs. It removes selectable text, interactive forms, links and accessibility tags, so keep your original. Text-heavy PDFs may become larger with this method; compare the output size before replacing a file.

When this tool is useful
Reduce a large scanned document
A scan saved at a very high resolution may be larger than needed for screen reading. Re-render its pages at a lower resolution and compare the downloaded file size with the original.
Prepare a PDF for an upload form
Choose the required pages and start with moderate quality. If the result still exceeds the form’s limit, reduce resolution or quality further while checking that important text remains readable.
Make an image-heavy reference copy
Use a flattened copy for visual review when interactive features are unnecessary. Preserve the original document if you need to search, fill forms or follow embedded links later.
Choose the right settings for your file
| Option | Use it for | What to know |
|---|---|---|
| Resolution | The number of pixels used for each page | Lower resolution saves detail as well as space; inspect small writing. |
| JPEG quality | The compression applied to page images | Low quality can introduce visible artifacts around letters and lines. |
| Pages | Selecting which pages appear in the result | Omitted pages are not included in the compressed copy. Leave blank to keep all eligible pages. |
Frequently asked questions
Practical answers about files, output and what this tool can do.
Will text still be searchable?
No. Pages are flattened into images. Do not use this method when searchable text, forms or accessibility tags must be preserved.
Is a smaller PDF guaranteed?
No. Scanned PDFs often benefit, but optimized or mostly text-based PDFs can get larger. The result message tells you when no size reduction occurred.
Can I compress a PDF to exactly 1 MB?
There is no automatic target-size setting. Adjust resolution and quality, download and check the reported result. Some documents cannot meet a small limit while remaining readable.
Does this PDF compressor preserve links and forms?
No. It rebuilds the selected pages as images. Links, interactive forms, selectable text and accessibility tags are not preserved.
