Compress PDF
Shrink PDF file size by re-encoding pages as quality-controlled images — right in your browser, so none of your files leave your device.
Shrink a PDF's file size by re-rendering its pages as images at a quality level you choose. High quality keeps pages sharp for printing, Balanced suits everyday sharing, and Small file squeezes every kilobyte out for email attachment limits and upload caps. A before-and-after size comparison shows exactly how much you saved.
Compression re-renders each page as an image, so the text in the result won't be selectable or searchable. For documents that are mostly text this may enlarge the file — “small file” mode helps photos.
How to use Compress PDF
- Upload the PDF you need to shrink.
- Pick a quality level — higher quality keeps pages crisp, lower quality produces a smaller file.
- Start the compression; each page is re-rendered and re-encoded directly in your browser.
- Compare the before-and-after sizes and download the compressed copy if you are happy with it.
Frequently asked questions
Is the text still selectable after compressing?
Compressed pages become images, so the original text layer is not carried over — treat the compressed copy as a sharing or upload version. Keep your original file for searching, copying and future editing.
How much smaller will my file get?
It depends on what is inside. Scans and photo-heavy documents often shrink dramatically, while text-only PDFs save less because their content was already compact. The size comparison shown after compression tells you the real number before you download.
Does my file get uploaded to be compressed?
No. Pages are rendered and re-encoded inside your browser using your device's own resources. The document never reaches a server, which also means there is no upload wait, no file size cap from our side and no copy left behind.
