No Upload Wait
Pages are processed on your device, so there is no upload queue. Processing time depends on the number of pages and your device.
Browser-Based Processing
Your documents are processed in your browser during the current session. Temporary data may remain in browser memory while the page is using the files.
How It Works
Each page is rendered as a JPEG image and placed into a new PDF. Text in the result can no longer be selected or searched.
How to use
LeedyBox PDF Compressor rebuilds the document from page images: each page is rendered in your browser, saved as a JPEG at the selected quality, and placed into a new PDF. This works best for scanned documents and image-heavy files. Text-based PDFs can become larger and lose selectable text, so compare the result with the original before replacing it.
- Click the drop zone or drag a PDF file onto it. Its name, size and number of pages appear.
- Choose a compression level. Recommended (about 86 DPI, JPEG quality 60%) suits reading on screen, email and uploads; Less Compression keeps pages sharper; Extreme Compression makes the smallest file, but small text can become hard to read.
- Click "Compress PDF & Download". Every page is drawn as an image, saved as a JPEG and placed into a new PDF with the same page size, while the progress bar counts the pages.
- The result is saved as name_compressed.pdf. Compare its size and legibility with the original, especially on pages with small print.
- If the result is larger or harder to read, try another level or keep the original. Click "Change File" to compress another PDF.
Frequently asked questions
Will text stay selectable after compression?
No. Every page becomes an image, so text can no longer be selected, searched, or copied, and small text can look softer at stronger settings. Keep the original file if you need searchable text.
Are my files stored on your servers?
No. Your PDF is compressed in your browser and is not uploaded to or stored on a LeedyBox server.
Why is the compressed file larger than the original?
PDFs that consist mostly of text or vector graphics are already compact. Turning their pages into images can increase the size. If that happens, keep the original file.
Which level should I choose?
Start with Recommended. Use Less Compression for documents with small print or fine drawings, and Extreme Compression only when a size limit matters more than legibility, for example a scan that has to fit an upload form.
What else is lost when the pages become images?
Links, form fields and bookmarks no longer work, and screen readers cannot read the text. Keep the original for anything that has to stay searchable, fillable or accessible.
Can I compress a PDF to an exact file size?
No. The size depends on how much detail the pages contain. If a file has to stay under a limit, try Extreme Compression, or divide the document into parts with Split PDF.
