Compress PDF to 500 KB
500 KB gives you more room than the tightest forms. Set the target, and Wispdf works in your browser until your PDF fits, then shows the size it reached.

Getting a PDF under 500 KB
To compress a PDF to 500 KB, set 500 KB as the target in Wispdf and add your file. Wispdf tries settings in your browser until it fits and tells you the size it reached. 500 KB can hold a multi-page text document with a few small images, or several scanned pages in grayscale. Long color scans may still need trimming.
Tips that help
- Several documents for one upload? Combine them with Merge PDF first, then compress the single file.
- Text pages cost little and scans cost a lot, so make PDFs from the original files when you can.
- Keep color only where it matters, like a photo ID, and scan the plain pages in grayscale.
Questions about compressing to 500 KB
What fits in a 500 KB PDF?
500 KB is enough for a multi-page text document, such as a resume, cover letter and reference list, often with a small photo or logo. Several scanned pages can fit too, especially in grayscale. A long color scan or a file full of photos is harder, and may need fewer pages or lower image quality to get there.
How do I combine documents and keep them under 500 KB?
Put them together with Merge PDF first. Then open Compress PDF to a Size, add the merged file and set 500 KB. Compressing once at the end is simpler than shrinking each part. Wispdf tells you the size it reached. If it's still over, find the heaviest pages, usually scans or photos, and trim or rescan those.
Is my file uploaded when I compress it to 500 KB?
Not unless you agree to it. Compress PDF to a Size runs on your device first, so your PDF stays in your browser. For very large or unusual files, we may offer our servers, and we always ask first. If you say yes, the file is encrypted on the way, deleted within an hour, and never looked at.
Why is my PDF still over 500 KB?
Often a few heavy pages carry most of the weight, such as a color photo or a page scanned at high resolution. Wispdf tells you the size it reached. To close the gap, rescan those pages at a lower resolution, convert the file with Grayscale PDF, try strong compression in Compress PDF, which is part of Pro, or split the file by size with Split PDF.
