Comprimir PDF
Reduza o tamanho mantendo a qualidade.
Compress PDF files to a smaller size without leaving your browser. Pick a compression level, shrink the file, and download it in seconds — no upload required. Because the whole process runs on your own device, compressing a PDF online here never means handing your file to a server first.
How to compress a PDF
- Drop your PDF file onto the page, or use Select files to choose it.
- Choose a compression level — Light, Recommended, or Strong — depending on how much you want to shrink it.
- Click Compress PDF to start processing.
- Check how much smaller your file got, right on the result screen.
- Download your compressed PDF.
Most compression websites work by uploading your PDF to their servers, shrinking it there, and sending a smaller file back — which leaves a copy of your document on a machine you don't control. Compressing in your browser skips all of that: a scanned ID, signed contract, or bank statement is processed on your own device and never transmitted, so no server-side copy of a sensitive file is ever created.
Common reasons to compress a PDF
- Get an attachment under the email limit — A scanned contract or multi-page report often lands just over your email provider's size cap. Compress it and the message sends on the first try, with no need to split the file.
- Fit a resume or portfolio into an upload form — Job portals and application forms frequently limit PDFs to a few megabytes. Trim a photo-heavy portfolio or design resume down to fit without dropping any pages.
- Save space on scanned receipts and records — Camera scans of receipts, IDs, and paperwork are image-heavy and add up fast. Compressing them frees storage on your device or cloud drive while every page stays readable.
FAQ
Does Compress PDF upload my files?
No. Compression runs entirely on your device inside your browser — your file is never sent to a server.
Can I compress a PDF offline, with no account?
Yes. There's no sign-up, and once the tool has loaded, compression works without an internet connection.
Will compressing reduce the quality of my PDF?
It depends on the level you choose. "Light" keeps quality closest to the original, while "Strong" shrinks the file more but can reduce image quality inside it — pick "Recommended" for a balance of both.
How much smaller will my file get?
It varies by file — PDFs with lots of images usually shrink the most. You'll see the exact size reduction on the result screen before you download.
Will the text in my PDF still be selectable after I compress it?
Compression re-saves each page as an optimized image to shrink the file, so selectable text becomes part of that image and can't be highlighted or searched afterward. It's ideal for scans and photo-heavy PDFs; if you need the text to stay selectable, keep your original.
Can I get the original quality back after compressing?
No. Compressing permanently re-saves the pages at a smaller size, and the download is a separate copy — your original file stays untouched on your device, so keep it if you might need the full-quality version later.
