SizeLock: NoResize Compress

SizeLock helps you compress images to a target file size while keeping the original resolution unchanged.

Choose one or more images, set a target size, and export compressed files locally to your device. SizeLock is designed for cases where upload forms require images under a specific size, but you do not want the app to resize or crop your image.

Key features:
- Compress images to a target file size
- Keep original resolution unchanged
- Import 1 to 9 images at once
- Use a slider or manual input for target size
- Save custom size presets
- Choose Auto, JPEG, PNG, or WebP output
- Preserve transparency when using PNG or Auto when needed
- Save output files locally to Pictures / SizeLock

SizeLock processes selected images locally on your device. Images are not uploaded to any server.

If a target size cannot be reached without reducing resolution, SizeLock will tell you instead of silently resizing your image.
