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 one JFIF file (JPEG variant from cameras and iPhones) to standard PNG at full natural size. Fixed output name converted.png — local Canvas work, unlimited saves.
Rotate one image with quick ±90°/180° buttons or a free 0–359° slider (plus numeric input), flip horizontal/vertical with toggles, and export PNG as rotated.png. Fix sideways phone shots in seconds — local Canvas work, unlimited saves.
Design simple logos with text, tagline, and 5 preset icons on canvas — export PNG/SVG. Draft startup marks in an afternoon — local Canvas work, unlimited saves.
Renders pasted HTML and CSS markup (no file upload, no URL screenshots) into downloadable PNG, JPEG (fixed quality 0.95), or SVG via the html-to-image library. Preview is DOMPurify-sanitized — free to start with no signup.
Pasted SVG masters first (infinitely scalable), or a square 1024px PNG/JPEG upload with centered subject. A 1024px source downscales crisply to all 14 slots; a 256px source upscales blurry — garbage in, blurry icons out.
Always the same 14: 1024 (App Store), 512 (Play/PWA), 192 (PWA), 180/120/87/60/58/40 (iOS), 167/152/76 (iPad), 32/16 (favicons) — flat in one ZIP, ready to sort into Xcode, Android Studio, or your web manifest.
iOS applies its squircle mask automatically — export full-bleed squares and let the OS mask them. Never pre-round: double-rounded icons look broken on device.
No — rendering runs locally in your browser on Canvas; artwork never leaves your device. Free covers 5 generations per session (the counter resets on reload); Pro is unlimited.
Image to ICO
Turn one image (PNG, JPG, WebP, or GIF) into a hand-built 32-bit Windows ICO — 6 sizes (16, 32, 48, 64, 128, 256) packed by default, or a single size (default 32). Center square-crop on, or fit with transparent/color background; alpha under 128 becomes transparent. Saves as <name>.ico.
