Reduce image file size with 4 quality presets. Keeps the original format (PNG, JPEG, WebP).
<h2>Why 100KB is the magic number</h2> <p>100KB is one of the most common upload limits worldwide. It is small enough to load fast on slow connections, yet roomy enough to keep portrait and document photos clearly readable. If a website rejects your photo as "too large", a 100KB target will almost always solve it.</p> <h2>Best for these uses</h2> <ul> <li>Passport-style portraits for online visa portals.</li> <li>Photo and signature uploads on banking forms.</li> <li>Profile pictures on educational and government platforms.</li> <li>Scanned IDs, certificates and proof of address.</li> </ul> <h2>Tips for crisp 100KB JPEGs</h2> <ul> <li>Start from a clear original — blurry photos lose more detail when compressed.</li> <li>Crop tightly first; smaller dimensions reach 100KB more easily.</li> <li>Avoid re-compressing the same image many times in a row.</li> </ul> <h2>Private and safe</h2> <p>The image stays on your device.
