Choose 500KB, 1MB, 2MB, 5MB, 10MB, or your own file size limit.
Compress for free in your browser. No account, installation, or file upload required.
This PDF contains CMYK images. Screen and email mode converts them to RGB, which may change printed colors.
This PDF is digitally signed. Compression will remove its signatures because they cannot be preserved.
Choose a size that matches your upload limit. Some PDFs cannot reach the selected target.
Useful for forms with strict size limits. Large originals may lose image quality or remain above the target.
Resize resumes, applications, and other documents for online submission.
A practical limit for attaching documents to web forms or sharing smaller files.
Useful when an email service or application portal has a 5MB upload limit.
Reduce the size of image-heavy documents for uploads and online sharing.
Enter a target between 0.5 and 100MB. The tool adjusts embedded image resolution and JPEG quality in steps.
Set a file size limit, such as 5MB. Image settings are adjusted in stages to try to get below it.
The tool primarily recompresses embedded images while keeping text and vector content where possible.
Your PDF is processed in your browser and is not uploaded to a server for compression.
Rather than turning every page into an image, the compressor keeps existing text and vector elements where possible and focuses on embedded images. If the original has a text layer, you can still search and copy text. It does not add OCR text to scanned PDFs.
Your browser loads, analyzes, compresses, and saves the PDF. Benri Lab does not receive your PDF for compression. No account or installation is required.
Drag and drop one PDF or choose a file from your device.
Select a 500KB, 1MB, 2MB, 5MB, or 10MB limit, or enter your own. Advanced settings let you adjust DPI and JPEG quality.
Check the original and output sizes, then download the result.
Photos and scanned pages are common reasons a PDF grows large. Files with many images often have more room for compression.
The tool reduces file size by adjusting embedded image resolution and JPEG quality. Lower settings can produce a smaller file but may make images look worse.
A PDF made mainly of text and vector graphics, or images already compressed, may shrink very little. Unsupported image formats are left unchanged.
Yes. It is free, with no account or installation required.
It depends on the original and your settings. Target mode adjusts image quality automatically; Advanced mode lets you control DPI and JPEG quality.
No. Loading, compression, and saving happen in your browser.
The tool keeps existing text layers while recompressing embedded images. Search and copy should continue to work when the original PDF contains text.
The tool tries progressively lower image settings. If the target is out of reach, it returns the smallest validated result. If nothing changes and the file cannot be reduced, it does not create an output.
Encrypted PDFs are not supported. Digital signatures cannot survive this compression process, so they are removed and the result explains what happened.
Yes, select the 5MB target. The result depends on the number of pages, embedded images, and existing compression. If 5MB is not possible, the tool shows the smallest validated result.
You can select a 1MB target. Large PDFs may lose noticeable image quality or remain above the target.
You can select a 500KB target. Image-heavy or long PDFs may be unable to meet such a strict limit.
PDFs made mostly of text or vector graphics, files with already compressed images, and PDFs with unsupported images may have little room to shrink.
No. The tool keeps the existing text layer where possible and mainly recompresses embedded images.
