About Image Compressor
Photos straight from a phone or camera are often too heavy for an email attachment or a web page. Add a file in one of the three supported formats, choose how hard to compress it, and it is re-encoded on our servers and shown next to the original with the new size. Width and height stay exactly as they were, so only the weight changes. You can also switch format while you compress, for example from PNG to WebP.
Features
- Quality slider from 10 to 100 in steps of 5, starting at 80
- Output as JPG, PNG or WebP, starting on your upload's format
- PNG output can reduce the color palette when there is no transparency
- Before and after size, width and height with a percentage-smaller badge
- Warns you when the result comes out larger than the original
Limitations
- Each file can be up to 60 MB, and pictures over 16384 px on a side or 100 megapixels in total are turned away at upload.
- A PNG with transparent areas is re-saved without losing colors, so it may shrink only a little; choosing WebP keeps the transparency too. JPG output fills transparent areas with white.
- The output carries no EXIF data, such as camera details or GPS tags.
- Downloading the compressed file needs a free account; without one you see a reduced-size preview.
How it works
- Drop a JPG, PNG or WebP file onto the upload area, or browse for it.
- Move the quality slider; lower values give a smaller file.
- Pick JPG, PNG or WebP as the output format. It starts on the format of the file you uploaded.
- Select Compress and wait for the result to appear beside the original.
- Check the size, width and height, switch between side by side and the slider view, then press Download.
Frequently asked questions
- There is no single safe value because it depends on the picture. Start at the default of 80, lower it in steps of 5 and check edges and text in the slider view. Each run starts from your original upload, so you can try several settings without compressing twice.
- That happens when the original was already well compressed. The page shows a warning in that case, and for PNG it notes that the format struggles to beat an already-compressed photo. Try a lower quality, or switch the output format to WebP or JPG.
- Width and height are unchanged; use the resizer for that. EXIF tags are not copied into the output, but the photo's rotation flag is applied to the pixels first, so a portrait shot still comes out upright.
- When the image has no transparency and quality is below 100, colors are reduced to a smaller palette with dithering. The tool keeps that version only if it is smaller than the lossless PNG, otherwise you get the lossless one.
- Yes, compression runs on our server, so the file is sent there. A result made while signed out expires after 24 hours and is then deleted automatically. Signed-in accounts keep results for as long as their plan allows.
