How to compress an image to 50KB
Upload your picture, leave Target size set to 50 KB, and choose Optimize image. The tool first searches for a suitable compression quality and reduces dimensions only if needed. Tiny file-size limits can noticeably reduce image quality.
- Choose your image. Select a JPEG, PNG, or WebP file from your device.
- Choose your output. Set Smart, Lossless, or a file-size target, plus dimensions and format.
- Preview and download. Check the actual final size and save the new image.
Frequently asked questions
Does this upload my photo to a server?
No. Image decoding, resizing, and encoding happen in your browser. Your photo is not transmitted to our hosting server. Only standard website files load from hosting.
Will the image keep exactly the same quality?
Lossless mode keeps the original file unchanged when possible or uses PNG without lossy compression. Smart Optimize can reduce the file size more, but it does not guarantee pixel-identical output. Very small target sizes require greater compromises.
What formats are supported?
This first version supports JPEG, PNG, and WebP. HEIC, GIF animations, SVG, and AVIF export are not included. Browser support can vary.
Can you guarantee the target size?
The tool attempts the requested maximum by adjusting compression and, if necessary, dimensions. If the target cannot be achieved within practical minimum dimensions, it clearly warns you rather than claiming success.
Can Enhance quality turn a blurry photo into a sharp HD original?
It can improve apparent sharpness and enlarge smaller photos, but it cannot recover missing detail, undo severe blur, or guarantee true HD. This version uses browser-based filters, not a trained AI super-resolution model.
What does KB mean here?
One KB is 1,024 bytes. For example, 100KB means no more than 102,400 bytes.
