Compress PDF

Select compression according to document type

PDF compression can help when files are too large to send via email, message, or upload form. The method in this tool renders each page into a JPEG image and then wraps it in a new PDF. This method is often useful for documents that are dominated by photos or scans, but is different from PDF optimization which preserves the original text and structure.

Choose a light level if detail and readability are more important, or a stronger level if size is a major concern. Size presets are a setting goal, not a guarantee; the number of pages, source resolution, and visual content determine the final size. The tool limits processing to 30 pages per PDF.

Check the quality before using the results

As pages become images, text can lose the ability to be selected, searched, or copied. Links, interactive forms, accessibility, bookmarks, layers, and digital signatures may also change or disappear. Do not use compressed results as a replacement for original documents if you need these features or if your organization requests searchable PDFs.

After compression, compare the file size with the limits of the destination form and enlarge several pages to check lowercase letters, numbers, barcodes, stamps, and signatures. If the text looks blurry or the file isn't small enough, go back to the source and optimize the image before re-exporting. Save the initial PDF so you still have a version with the full quality and structure.

Additional limits and checks

Processing requires browser memory to render each page. Close unnecessary tabs if your device is slow, and don't run several large documents at once. If the resulting file is larger or too blurry, stop using that copy and return to the original PDF; presets do not promise a specific target.
