Nothing leaves your device. Everything is processed here.

SocialShrink's image compressor reduces the file size of your photos and images directly in your browser. We don't upload anything to any server: your file loads into your device's memory, gets compressed using the Canvas API and Web Workers, and you download the result. Works with JPG, PNG and WebP. You can choose a manual quality level or set a target size in KB and the binary search engine will find the best balance between weight and visual fidelity.

How it works

  1. Drop your image
    Drop a JPG, PNG or WebP image into the upload area. You can upload multiple images at once for batch processing.
  2. Choose how to compress
    Select quality mode (choose the level from 1 to 100) or target size mode (specify how many KB the result should weigh). The engine adjusts compression automatically.
  3. Download the result
    Your compressed image is generated instantly. You'll see how much weight you've saved and can download it with a single click. The original file never leaves your device.

Your privacy

Your image is not uploaded to any server. All processing happens in your browser using Web Workers. When you close the page, nothing remains anywhere. No account, no database, no third parties.

Frequently asked questions

Is quality lost when compressing?
It depends on the level you choose. At quality 80, the visual difference is practically imperceptible on screen. The engine never inflates the file: if the result weighs more than the original, it returns the original intact.
What formats does it accept?
JPG (JPEG), PNG and WebP. For iPhone photos in HEIC format, use our HEIC conversion tool.
Does it work offline?
Yes. Once the tool is loaded, you can compress images without an internet connection because everything runs in your browser.
Is there a size or file limit?
There's no artificial limit. The only limit is your device's memory. You can process images of several MB without any problem.
What's different from other online compressors?
Most of them upload your image to their server for compression. SocialShrink has no processing servers. We technically can't see your image because we never receive it.
