Queue RAW files (CR2, NEF, ARW, DNG, RAF, ORF, RW2, PEF, SRW) — each gets a live browser decode test with a green/red dot; supported ones convert to JPG, PNG, or WebP at quality 10–100% (default 92, hidden for PNG), one by one or all at once. Canvas re-encoding drops metadata — local processing, unlimited saves.

Sharpen soft photos with a 3×3 convolution kernel (center 1+4f, arms −f, f = max(0.5, intensity)) — or add Gaussian/motion blur artistically. Intensity 1–10 (default 5); motion kernel caps at 15px with 0–360° angle; live 400px preview debounced 150ms; JPG/PNG/WebP output (quality default 0.92) — local processing, unlimited saves.
Convert a batch of images to one output — JPG, PNG, or WebP — at quality 10–100% (default 80%), capped at 4096px longest side, then download everything as a ZIP. Files that fail conversion fall back to their originals inside the same archive — local library work.

Design sized social posts with text overlays and brand colors in 4 network sizes. Ship a week of creatives in one sitting — local Canvas work, unlimited saves.
Only files your browser can actually decode — the tool tests each upload live and marks failures red with external-editor guidance. True sensor-data RAWs usually fail; files carrying an embedded decodable preview pass.
RAW for exposure recovery and white balance latitude; converted JPG/PNG for sharing and quick edits. Convert working selects, archive RAW masters.
Developed output bakes in a canvas re-encode at your quality setting (default 0.92) — keep RAW originals for re-edits. Metadata is dropped in the re-encode, so converts carry no EXIF.
No — conversion runs locally in your browser. Saves never touch a meter — downloads on local tools are unlimited.
