How to use it
- Choose your photo or drop it into the box.
- Keep the target at 75 KB, or change it to any size you need.
- Check the preview, then download the new file.
Why 75KB?
75KB is a common limit for photo uploads that allow 100KB or less. 75KB keeps faces clear and sits comfortably under a 100KB cap.
How it works: the tool tries the best JPEG quality that fits under your limit. If quality alone is not enough, it reduces the image dimensions a little at a time until the file fits. Everything happens inside your browser tab, so there is no upload, no account and no watermark.
Tip: if the result looks too soft, crop away empty space first (a smaller picture needs less compression) or raise the target a little.
For the best result at 75KB: (1) crop away empty background, (2) if the form also wants exact pixels, resize first, (3) compress last, because every extra save as JPG adds small artefacts. Keep your original photo in case you need a different size later.
Typical file sizes: a modern phone photo is 2 to 6MB, a screenshot PNG is 300KB to 2MB, and a passport-style crop of 600×600 pixels is usually 60 to 200KB before compressing. Getting to 75KB therefore means reducing the file noticeably, which is why the tool lowers quality and, if needed, dimensions.
Size facts for 75KB: it equals 76,800 bytes (0.073 MB). At ordinary JPEG quality that holds roughly 640×480 to 910×680 pixels of a typical 4:3 photo; detailed pictures sit near the low end, smooth ones near the high end. Compared with a typical 3MB phone photo, a 75KB file is about 98 percent smaller.
Nearby limits: if your form has a different cap, try 70KB (a smaller cap) or 80KB (a larger cap). Other forms may name different caps, so always read the exact limit on the upload page.

Questions
How do I compress an image to 75KB?
Choose your photo, keep the target at 75KB and download the result. The tool finds the highest JPEG quality that fits under 75KB and only shrinks the dimensions if it has to.
Is my photo uploaded to a server?
No. Compression runs entirely in your browser, so your image never leaves your device.
Will the quality drop at 75KB?
Some loss is unavoidable when a file gets smaller, but the tool keeps the best quality that still fits the limit. Photos with fine detail lose more than simple images; raise the target if the result looks too soft.
Which formats work?
JPG, PNG and WebP can be used as input. The output is always a JPG, the format that gives the smallest file for photos. Transparent areas of a PNG become white.
Why is my file still bigger than 75KB?
Very large originals (for example 6000 pixels wide) with lots of detail need to be shrunk in dimensions as well. The tool does this automatically. If you still see a larger file, make sure you downloaded the new file and not the original, and try cropping the picture first.
What is the best way to keep a face sharp at 75KB?
Crop so the face fills the frame, use a photo taken in good daylight, and avoid screenshots of photos. A sharp, evenly lit original compresses much better than a dark or blurry one.
Can I compress several images to 75KB?
Yes. Compress them one after another; each file is handled separately in your browser and nothing is uploaded.
Does the picture change shape?
No. The aspect ratio stays the same. If a form needs exact pixels, resize first with the <a href="/resize-image/">resize tool</a> and then compress.
How many pixels fit in 75KB?
Roughly 640×480 to 910×680 pixels for a normal photo, depending on detail. If your form also states exact pixels, resize first and compress last.
How much smaller is 75KB than a phone photo?
Compared with a typical 3MB phone photo, a 75KB file is about 98 percent smaller.
