Preset loaded: 1080 px, high quality floor — the size Instagram serves, so it won't recompress your upload as hard.
Portal limits change — double-check the current notification before you submit.
Quality is lowered only as far as the floor allows. If that still isn't enough, the image is scaled down in small steps instead — downscaling looks far better than heavy compression artifacts. EXIF metadata (location, camera, serial numbers) is always removed for your privacy; colour accuracy is kept.
Instagram re-encodes everything; uploading at exactly 1080 px wide with high quality gives its encoder the best possible input and your feed the sharpest result.
Type the size your form demands — 20 KB, 50 KB, 1 MB — or pick a preset. The result always lands just under it.
JPEG, PNG, WebP, GIF, BMP — one file or a whole batch. The engine finds the highest quality that fits your limit.
Every pixel is processed inside your browser. Your ID photos and signatures never leave your device.
Nothing is uploaded — the compression runs inside your own browser using its built-in image engine. That means no size limits, no waiting for uploads, and no copies of your ID photos or signatures on anyone's server. EXIF metadata such as GPS location is removed from the output automatically, while colour profiles are preserved.
