Why compress an image?
Phone photos are often several megabytes each. That makes them slow to upload, hard to send on forms and job portals, and heavy for websites. Compression shrinks the file while keeping it looking the same to the eye.
Step-by-step
- Upload the image to the Image Compressor tool.
- Set the quality. Start around 75–80% for photos. The tool shows the original size and the new size side by side.
- Choose the format. JPEG is best for photos. PNG suits images with text, logos, or transparency, but produces larger files.
- Download the result and compare it with the original before you use it.
Tips
- For most photos, 75–80% quality looks identical to the original but cuts the size by half or more.
- If the image still looks soft, raise the quality a little instead of starting over.
- Avoid compressing the same JPEG again and again — each round loses a little detail. Always keep your original file safe.
- Large dimensions also make files big. If a photo is 4000 pixels wide but will only be shown small, resizing it first shrinks the file even more.
Compression happens entirely in your browser, so your photos are never uploaded anywhere.
