Make Round Image uses the HTML5 Canvas 2D API — the same rendering engine every web browser ships with. Your image is decoded into a pixel buffer, transformed in memory, and re-encoded to PNG or JPEG when you download. No server involved.
Make Round Image accepts PNG, JPG, WebP, GIF, and BMP inputs. Output defaults to PNG (lossless) or JPEG (smaller size) depending on the operation.
Make Round Image preserves pixel data exactly when the target format is lossless (PNG, WebP-lossless). Lossy targets (JPEG) accept a quality trade for smaller size.
Make Round Image handles images up to about 50-megapixels on a typical laptop (roughly 8000×6000). Above that, browser memory becomes the bottleneck.
Yes — nothing uploads. Your image is decoded, transformed, and encoded entirely in browser memory. Close the tab and there's no trace anywhere.
All free, all browser-based, all zero-signup.
