JFIF is JPEG data with a different container label — common from cameras, iPhones, and scanners. Many apps reject the .jfif extension despite understanding the pixels perfectly.
Lossless PNG preserves every pixel for editing at the full natural size. No JPG option exists here — for JPG output use the Convert to JPG tool instead.
No batch mode: one file converts per run and always downloads as converted.png — rename it yourself when converting folders of .jfif one by one.
No — conversion runs locally in your browser on Canvas. Only saves touch the network — downloads are unlimited.
Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
