PixSize is a lightweight image compressor brand built on the ExactSize engine. It focuses on one thing only: helping you compress JPG or PNG files to an exact file size in KB or MB, instead of just giving you a rough “smaller file”.
This makes PixSize especially suitable for online forms, job portals, passport and visa systems, education portals, and government websites that strictly require a maximum file size such as 50KB, 100KB, 200KB, or 500KB. You can also use it to prepare profile photos, ID document scans, and attachments for email or messaging tools that enforce upload limits.
Unlike traditional “compress image” tools that only provide a percentage slider, PixSize lets you set a precise target in KB or MB. The ExactSize engine then automatically adjusts compression parameters and re-encodes your image so that the final file size is as close as possible to your target, while preserving visual clarity.
All compression is performed in your browser. Your images are not stored on a server, which means your passport photos, ID documents, and personal images stay on your own device. You can use PixSize directly in the browser without registration, download the result instantly, and repeat the process as many times as needed.
