Compress PDF
Compress PDF shrinks file size right in your browser — no upload, no daily limits and no page caps. Only the raster images inside the PDF are re-encoded (lower resolution and JPEG quality); fonts, text and vector graphics are left 100% untouched, so text stays as sharp as the original. Pick one of three strength presets, or enter a target file size and let the tool find the right level for you.
When do you need it?
- Email an application whose PDF exceeds the attachment limit (usually 10–25 MB).
- Submit an online form with a strict size cap such as “file must be under 2 MB”.
- Shrink a multi-page scan bundle for storage or for sending over messaging apps.
- Lighten an image-heavy catalogue so it downloads faster on phones.
- Hit an exact required size without dropping any pages.
Key features
- Three presets: Extreme (max 900px) · Recommended (1600px) · Less (2400px).
- Target-size mode: enter the KB you need and the tool steps down through 10 levels until it fits.
- Only raster images are re-encoded — fonts, text and vectors are untouched, so text never blurs.
- Shows before → after size and the exact percentage saved.
- Runs entirely in the browser: free, unlimited and with no signup.
How to use
- Upload or drag & drop your file — everything runs right in your browser.
- Pick your options and hit the process button.
- Download the result — fast, free, no account required.
Safety & privacy
Your PDF is compressed entirely in the browser with pdf-lib and the Canvas API — never uploaded, stored or shared. Contracts, personal records and internal documents never leave your machine, unlike online compression services that require uploading to their cloud.
Genuinely free — no limits
KitsyApp is 100% free — no signup, no daily limits, no watermarks. Processing quality is on par with paid tools like Smallpdf or iLovePDF, and your files are processed on your own device instead of someone else's server.
Frequently asked questions
Does compressing a PDF blur the text?
No. Only the raster images inside the PDF are re-encoded; fonts, text and vector graphics are kept 100% intact, so text stays sharp at every compression level.
Can I compress down to an exact required size (e.g. under 2 MB)?
Yes. Pick target-size mode and enter the KB you need — the tool steps down through progressively stronger levels until the file fits (or reaches the smallest feasible size) and reports the result.
Is there a page or file size limit?
No. Compression is completely free, with no limit on pages, runs or file size, and no account required. Larger files simply take longer because every image has to be re-encoded.
Will a text-only PDF (no images) get smaller?
Very little or not at all, because the tool only re-encodes raster images. Text-only PDFs are already small; try converting to another format or trimming content if you need more savings.
