Resize hundreds of photos to one exact W×H canvas (default 800×800, inputs 1–10000px) with Contain, Cover, or Stretch fit — no percentage or preset modes. Transparency flattens onto white; output is always PNG. Photographers deliver 400 wedding shots at uniform size — local Canvas work, 2 free batches a day.
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.
Convert AVIF images to lossless PNG in your browser — transparency and quality preserved for editing for editing and compositing work.
Renders a scannable QR code from any text or URL with a client-side Reed-Solomon encoder at fixed high error correction. Customize size, colors, and center logo, then download the PNG — free, local, no signup.
Generate favicon packages — PNG icons plus Apple touch icons — from one image. Note: the .ico file is PNG data renamed (modern browsers only). Ship every platform icon in one pass — local generation, unlimited saves.
PNG (Portable Network Graphics) uses lossless encoding and is best for graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. AVIF (AV1 Image File Format) uses lossy or lossless encoding and excels at next-gen web images — royalty-free format with better compression than WebP and JPEG. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Typically 30–50% smaller than PNG with transparency intact — biggest wins on photos.
Both — AVIF handles gradients and flat color better than PNG.
Editing masters and pixel-exact screenshots stay PNG for lossless re-edits.
No — conversion runs locally in your browser; unlimited saves on local tools.

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.
