Resize and compress images to an exact file size
Uploading a photo to a government portal, a job application, or a web form often comes with a strict size limit — "maximum 100KB", "under 50KB", "no larger than 200KB". Most image editors only let you pick a quality percentage and hope for the best. PixelPress works the other way around: you tell it the exact size you need, and it finds the settings that get you there.
How the exact-size algorithm works
For lossy formats like JPG and WebP, PixelPress runs a binary search on the quality value. It encodes the image, measures the real file size of the resulting data, and narrows in on the highest quality that still fits under your target. Because it measures the actual generated file — not an estimate — the number you see is the number you get.
If the smallest possible quality still isn't enough (common when a huge photo needs to become a tiny thumbnail), PixelPress gradually reduces the pixel dimensions and searches again, stopping the moment your file fits. A hard iteration cap prevents it from ever looping forever.
Choosing the right format
JPG is the safest choice for photographs and is accepted almost everywhere. WebP produces noticeably smaller files at the same quality and is ideal for modern websites. PNG is best for graphics, logos and screenshots with sharp edges or transparency — but because it is lossless, it can't hit tiny sizes without shrinking the image.
Privacy by design
Traditional online compressors upload your images to their servers. PixelPress never does. All the work happens in your browser tab, which means your private photos, documents and ID scans stay on your machine. Nothing is transmitted, logged or stored.
