Works entirely in your browser. No uploads. No watermarks. No signup.
Email attachments have a 10 MB or 25 MB limit. College portals ask for documents under 2 MB. Government job sites often reject files above 500 KB. If your PDF keeps getting rejected because it is too large, you need a fast and reliable way to compress it โ without ruining the content inside.
QuickPDFonline's Compress PDF tool shrinks your PDF directly in your browser, making it small enough to email or upload anywhere. All processing happens directly in your browser โ your files are never uploaded to any server. Whether it's a salary slip, a legal document, or a government ID scan, it stays completely private on your device.
Students submitting to college portals, job applicants uploading documents, and professionals sharing large reports by email will find this tool saves them time and frustration โ for free, every time, with no sign-up needed.

You set the target โ the tool automatically finds the right compression level to match it. A 10 MB diagram file can reach 45 KB. Results depend on content type.
For very aggressive compression (e.g. 10 MB to 45 KB), text becomes part of the image and may appear slightly soft. For moderate targets (e.g. 500 KB), readability remains very good.
Never. Compression runs entirely inside your browser using JavaScript. Your file is never sent to any server โ safe to use with confidential documents like bank statements, salary slips, or government ID scans.
Just type 1 in the target size field and select MB. The tool uses binary search across multiple quality levels to get as close as possible to your exact target.
