To compress an image, upload it to DIT ToolsKit's Image Compressor, adjust the quality slider (and optionally set a maximum width and height), then click Compress. You get a smaller JPEG with the size reduction shown instantly.
What is Image Compressor?
Image Compressor shrinks a photo or graphic's file size by adjusting its JPEG quality and, optionally, its dimensions — useful whenever a file is too large to upload, email, or load quickly on a website.
How to use Image Compressor
- Upload the image you want to shrink.
- Adjust the quality slider — lower quality means a smaller file.
- Optionally turn on "Also limit dimensions" and set a max width and height.
- Click "Compress image" and download the result.

Frequently asked questions
What image formats can I compress?
You can upload PNG, JPEG, WEBP and most common image formats — the compressed output is saved as JPEG.
Will compressing make my image blurry?
Lowering the quality slider does reduce fine detail — for most photos, 60-80% quality keeps them looking sharp while cutting file size significantly.
Can I resize and compress at the same time?
Yes — turn on the dimension limit option to shrink the image's width and height alongside its quality in a single step.
