Use Adjust Colors to fine-tune brightness, contrast, saturation and more in your PDF, directly on your device and without sending your file anywhere. It gives you precise control over the contents and appearance of each page, with a live result you can download immediately.
Processing is powered by WebAssembly — the same technology behind professional desktop PDF software — so the tool stays fast even on large or complex documents, and works the moment the page loads. No file ever leaves your device. The tool works entirely client-side, which makes it safe for confidential, financial, and personal documents.
There is no sign-up, no usage cap, and no watermark on the result. It runs in any modern browser on both desktop and mobile devices.
