Compress images to exact target sizes (e.g., 20KB, 50KB) or custom quality ratios with batch support. Dramatically reduce file sizes while preserving crisp pixel clarity for portal uploads, email limits, and web speed.
Three simple steps to get your file size right for any upload form.
Drag and drop your JPG, PNG, or WebP file into the upload box. The process is instant and private.
Choose your desired limit: Under 20KB, 50KB, 100KB, or 200KB. This tells the engine exactly how much to compress.
Click Compress and download your new file. Check the properties to confirm the KB size meets your requirement.
Solve strict file size requirements for official documents and digital platforms without losing quality.
Meet the strict <240KB or specific KB limits for DS-160, N-400, and Green Card applications. Ensure your 2x2" photo passes automated USCIS validation.
