Compress PDF
Reduce PDF file size — rasterize pages, or recompress images while keeping text selectable.
Processed entirely in your browser. "Rasterize" converts each page to an image, so text in the output is no longer selectable. "Preserve text" keeps text, fonts and vector content untouched and only recompresses embedded JPEG images.
- Free with no sign-up, no watermark and no daily task limit.
- Two compression methods: rasterize for maximum shrinkage on scans/photos, or preserve text for documents you still need to search and select text in.
- Compress up to 20 PDFs at once and download them as a ZIP.
- Runs entirely in your browser — your files are never uploaded.
- Combined before/after size comparison across the whole batch, so you can pick the smallest quality that still looks right.
- Good for getting under email attachment and upload-form size limits.
Why this is private

- Open your browser's DevTools → Network tab while using this tool — you won't see a request carrying your input, because it never leaves your device.
- Nothing you enter is uploaded to a server or shared with us — the processing happens entirely on your device.
Overview
Reduces PDF file size, batch-processing up to 20 files at once. Two methods: "Rasterize" converts each page to a compressed image — effective for scanned or photo-heavy PDFs, but text is no longer selectable. "Preserve text" leaves every page's text, fonts and vector content completely untouched and only recompresses embedded JPEG images, so a text-heavy report or contract stays searchable and selectable after compressing.
How to use it
- 1Choose "Rasterize" or "Preserve text" depending on whether you need the result's text to stay selectable.
- 2Choose a compression level.
- 3Drop one or more PDFs.
- 4Download each result, or all of them as a ZIP.
Tips
- Rasterize gives the largest size reduction and works on any PDF, but text becomes part of the page image and can't be selected, searched or copied afterward.
- Preserve text is the right choice for a text-heavy contract or report where searchability matters — it only shrinks embedded images, so a nearly-all-text PDF will barely shrink at all, which is expected, not a bug.
Frequently asked questions
What people use it for
Compress a contract without losing searchable textUse Preserve text so recipients can still select, copy and search the document after compressing.
Get a batch of PDFs under an email attachment limitGmail and most providers cap attachments around 25 MB; drop a whole folder and compress them all in one pass.
Shrink a scanned document for an upload formJob portals and government sites often reject files over 1–2 MB — Rasterize mode on a scanned multi-page PDF usually compresses well past that.
Reduce a photo-heavy report or portfolioPages built from screenshots or photographs are where Rasterize mode saves the most.
