Compress PDF & Reduce PDF Size
Compress PDF files free, right in your browser — your PDF is never uploaded. Most of the size of a scanned or photo-heavy PDF is the images inside it, so this PDF compressor re-encodes those images and leaves text, links and form fields as they are. Pick a compression level or type a target size in KB, then download the smaller PDF.

Features
Smaller images, same text
The Recommended level re-encodes the JPEG images in the PDF at 150 DPI. Text, vector graphics, links and form fields are copied unchanged, so the text stays selectable and searchable.
Compress to a target size
Type a size in KB, for example 200. The tool lowers image resolution step by step (150, 120, 100, then 72 DPI) until the PDF fits, and says so when it cannot get that small.
Three compression levels
Recommended (150 DPI), Smaller (100 DPI, lower image quality) and Smallest. Smallest turns every page into an image for the smallest file; text in that version can no longer be selected.
Up to 20 PDFs at once
Sign in for free to compress up to 20 PDFs in one batch and download them together as a ZIP. Each PDF can be up to 200 MB on a computer and 100 MB on a phone or tablet.
Never bigger than the original
If compressing does not make a PDF smaller, you get the original file back unchanged instead of a bigger copy.
Free, no watermark
There is no watermark, no page limit on the image levels and no account needed for a single PDF.
Use cases
Online forms with a size limit
Application, exam and job portals often reject PDFs over a set size. Type the limit as the target size and download a PDF that fits.
Email attachments
Shrink a scanned contract or a photo-heavy report so it fits under your email provider's attachment limit.
Phone scans
PDFs from phone scanner apps store each page as a large photo. Recompressing those photos usually removes most of the size.
Private documents
IDs, contracts and bank statements are compressed on your own device, so the file is never handed to a third-party server.
How to compress a PDF
Add your PDFs
Drop one or more PDFs into the box, or click Select PDF.

Download the smaller PDF
Compare the before and after size on each card, then download one PDF or all of them as a ZIP.
Frequently asked questions
No. Recommended and Smaller only re-encode the images in the PDF; text and vector graphics are not touched, so they stay sharp and selectable. Only Smallest turns pages into images.
