I built Kompresly because job portals and email still demand photos under 200 KB or 500 KB, and most phone tools upload your file to compress it. Kompresly runs on-device: pick a target size (200KB / 500KB / 1MB or custom), batch photos, compare before save. JPEG, PNG, WebP, HEIC. If hitting the size would wreck the image, it keeps the best effort and tells you. No account. Free with ads.
