Reduce PDF file size by re-rendering each page at a lower resolution. Choose from three quality levels — Maximum for the smallest file, High Quality for better appearance, or Balanced as a middle ground. Works well on image-heavy documents.
or click to browse — works on large files too
The tool reduces file size by re-rendering each PDF page as a JPEG image at your chosen quality, then assembles them into a new PDF. This is particularly effective on image-heavy documents where visual content drives the file size.
Maximum renders at lower resolution for the smallest output — good for sharing or email. High Quality preserves more detail with moderate size reduction. Balanced sits between the two.
Your PDF is rendered and re-encoded using JavaScript running locally. It is not uploaded to a server at any point during the compression process.
After compression, the tool shows the original size, the compressed size, and the percentage saved — so you can decide whether to keep the result or try a different quality level.
The compressed PDF downloads automatically when processing completes. Your original file is not modified — the tool creates a new compressed copy.
Drop your PDF onto the upload area or click to browse. The file stays on your device throughout the process.
Select Maximum for the smallest file size, High Quality to preserve more visual detail, or leave it on Balanced for a reasonable middle ground.
Click "Compress PDF." The tool shows the original and new file sizes with the percentage saved, then downloads the compressed copy automatically.
This tool works by re-rendering each page as a JPEG image. JPEG encoding is lossy — the Maximum setting applies more compression and will reduce image sharpness compared to the original. The High Quality setting applies less compression and produces output that looks closer to the original, at the cost of a smaller file-size reduction. Text may become slightly less crisp at higher compression levels, so use Maximum for sharing or email and High Quality when the document will be read closely or printed. The savings report lets you try a setting and compare the result before deciding.
The tool runs in desktop and mobile browsers. On a phone you can open a PDF from your device storage or cloud app, choose a quality level, and download the compressed result — no app required. Processing speed depends on your device and the size of the document.
