Image Compressor

Image Compressor shrinks photo file sizes — often by 50–90% — with a quality slider so you control the tradeoff. It shows you exactly how many bytes you saved, which makes it perfect for web uploads, email attachments, and storage limits.

When to use it

Use it when files are too big: a website caps uploads at 2 MB, email rejects a 15 MB attachment, your phone storage is full of 4 MB photos, or a page loads slowly because of giant images. Anywhere file size matters more than pixel-perfect quality, compression is the answer.

How to use it

  1. Open Image Compressor and upload your image (JPG, PNG, or HEIC).
  2. Move the quality slider. Lower = smaller file. The preview shows the result before you commit.
  3. Check the "bytes saved" readout to see the before/after sizes.
  4. Download the compressed image. One image = one document of quota.

What the output looks like

The same image, same dimensions, smaller file — delivered in an efficient modern format. A 4 MB phone photo typically becomes 400–800 KB with no visible difference at normal viewing sizes.

Good to know

  • The slider is the whole game. Around 80% quality is the sweet spot for photos: big savings, no visible loss. Below ~60%, you'll start seeing artifacts in skies and gradients.
  • Dimensions don't change — only the file size. If you also need smaller pixel dimensions, resize first, then compress.
  • PNG screenshots with text compress less dramatically than photos; that's normal, not a malfunction.
  • Compressing an already-compressed image gives diminishing returns. Start from the original when you can.
  • Keep the original if the image matters (client work, printing). Compression is one-way — you can't get the discarded data back.
