Compress Image to 100KB
Upload an image and we shrink it to 100KB for you — automatically adjusting quality and, if needed, dimensions so it fits the target.
We aim for 100KB. To get there we lower the image quality first and, only if that is not enough, reduce its dimensions — so your file reliably reaches the target. You will see the exact final size after compression.

Why 100KB?
100KB (kilobytes) is a common upload ceiling: government and visa portals, job-application forms, exam registrations, and many web forms cap profile photos and document scans at exactly 100KB. Email newsletters and fast-loading web pages also favour images around this size. Instead of guessing quality settings yourself, this tool works backwards from the 100KB goal and does the maths for you.
How We Reach the 100KB Target
There is no magic that shrinks any image to 100KB without a trade-off — a 12-megapixel photo simply holds more data than 100KB can store at full quality. So our compressor is transparent about how it gets there: first it lowers the JPG/WebP quality (or the PNG colour palette) step by step. If the file is still above 100KB at the lowest sensible quality, it then reduces the pixel dimensions until the target is met. The result is the highest-quality version of your image that still fits in 100KB.
Best For Photos and Full-Colour Images
Photographs, screenshots with gradients, and colourful graphics reach 100KB reliably because their quality can be tuned smoothly. Save these as JPG or WebP for the smallest result. A large, detailed PNG photo is the one case where 100KB may not be reachable without heavy downscaling — PNG is a near-lossless format built for sharp graphics and logos, not photos. If you hit that wall, converting the photo to JPG will get you well under 100KB.
Your Dimensions Are Kept When Possible
Whenever the target can be met by quality alone, your image keeps its original width and height — only the file size drops. Resizing only kicks in as a last resort to honour the 100KB limit, and the tool tells you the new dimensions so there are no surprises. This order (quality first, size second) preserves as much detail as the target allows.

Frequently Asked Questions
Can any image be compressed to exactly 100KB?
For photos and full-colour JPG or WebP images, yes — we tune the quality and, if needed, the dimensions to land at or just under 100KB. The one exception is a large, detailed PNG photo: PNG is near-lossless, so reaching 100KB may require heavy downscaling. In that case we return the smallest version we can and suggest saving as JPG instead.
Will compressing to 100KB reduce the quality?
Usually a little, yes — that is the honest trade-off of hitting a fixed size. We always keep quality as high as the 100KB target allows, and for typical photos the result still looks sharp on screen. Larger source images lose more than already-small ones.
Does it change my image's width and height?
Only if it has to. We reduce quality first and keep your original dimensions whenever that is enough to reach 100KB. Resizing is a last resort, and we show you the new dimensions in the result.
What if my image can't reach 100KB?
You will still get the smallest file we could produce, along with a note explaining that 100KB was not reachable without unusable quality. For photos, re-uploading as a JPG almost always solves it.
Which formats are supported?
JPG/JPEG, PNG, and WebP up to 20MB each. JPG and WebP compress to a target most smoothly; PNG works best for graphics and screenshots rather than large photos.
Are my uploaded images private?
Yes. Uploads use a 256-bit SSL encrypted connection and every file is automatically deleted from our servers within one hour. We never add watermarks.
