Accepts JPG, PNG, WebP — max 50 MB
Original file: --. We'll find the best quality to hit your target.
Unlike other image compressors that only give you a quality slider, ClearUtil lets you set a target file size. Need your image under 2MB for an email attachment? Under 500KB for a web upload? Just enter the size you need and we'll automatically find the best quality setting to hit your target.
Upload any JPG, PNG, or WebP image. Choose between two compression modes: Quality Slider lets you manually set the compression level and instantly see the estimated output size before compressing. Target File Size lets you enter an exact size (like 1MB or 200KB) and our tool automatically adjusts the quality to match your target as closely as possible.
Many platforms have strict file size limits: email attachments (25MB), Discord (8MB free), WhatsApp (16MB), forum avatars (500KB), job application uploads (2MB). Instead of guessing with a quality slider and re-compressing multiple times, just enter the limit and get the result in one step.
How accurate is the target file size? The tool gets within 5-10% of your target in most cases. It uses binary search across quality levels to find the best match.
Are my images uploaded anywhere? No. Everything runs locally in your browser. Your images never leave your device.
What format should I use? JPEG is best for photos. WebP gives 25-35% smaller files than JPEG. PNG is best for graphics with transparency.
