Need a photo under 100 KB for a job portal, government form, or website upload box that keeps rejecting your file? This tool gets you there in seconds — and it never sends your image anywhere. Everything happens inside your own browser using the Canvas API, so the picture on your screen is the only copy that exists.<br>Drop in a JPG, PNG, WebP, AVIF, or even an iPhone HEIC photo and the compressor automatically dials the quality down just far enough to slip under the 100 KB ceiling while keeping the result as sharp as possible. Instead of guessing at a quality percentage, it runs a quick binary search on the encoder: it tries a setting, measures the actual file size, and narrows in until it finds the highest quality that still fits your target. You see the before and after size and the exact percentage saved for every file.<br>Uploading a smaller image isn't just about passing a validation check. A 100 KB photo loads almost instantly on slow mobile connections, costs less in data, and won't get silently down-scaled by the platform you send it to. For ID photos, profile pictures, and document attachments, 100 KB is the sweet spot most systems accept.<br>You can process several images at once and download them individually or all together. If a file is already smaller than the target, it's left untouched so you never lose quality for no reason. Because nothing is uploaded, there are no file-size caps imposed by a server, no queue, and no privacy trade-off — close the tab and every trace is gone.
Frequently asked questions<br>How do I compress an image to exactly 100 KB? Drop your image into the tool and it automatically lowers the JPEG quality until the file lands at or just under 100 KB. You can change the target in the “Target (KB)” box if you need a different size.<br>Will compressing to 100 KB ruin the quality? The tool keeps the highest quality that still fits 100 KB by searching for the best setting rather than over-compressing. Small photos may look identical; very large or detailed images will lose some fine detail, which is unavoidable at small file sizes.<br>Are my images uploaded to a server? No. All processing runs locally in your browser with the Canvas API. Your files never leave your device, so there is nothing to delete and no privacy risk.<br>Can I compress HEIC photos from my iPhone? Yes. HEIC and HEIF files are decoded in the browser and can be compressed to 100 KB and saved as JPG, which is accepted everywhere.<br>Is there a limit on how many images I can compress? There is no server, so there is no hard limit. You can drop in many files at once; the practical ceiling is just your device’s memory.
