🗜️ Image Optimiser Studio

Each file is decoded with the browser's own image decoder, redrawn onto a canvas at the target dimensions (aspect ratio preserved, never upscaled), then re-encoded with canvas.toBlob(). The byte count you see is the size of the actual file you would download, not an estimate. WebP encoding is probed at start-up; browsers that cannot produce it fall back to JPEG automatically. Transparency only survives in PNG or WebP output — JPEG fills transparent pixels with the page background. Re-encoding also strips EXIF metadata (including any GPS location your phone embedded), so the studio doubles as an offline compressor, resizer and metadata scrubber. Nothing is uploaded: there is no server here to upload to.
