Tools by category
40 pagesStraight from the tool catalogue. Categories overlap deliberately — a utility that operates on images is listed under both — so these group totals add up to more than the catalogue holds.
Image26
Image Background Remover
Remove backgrounds from PNG, JPG, WebP, AVIF, and HEIC. Batch up to 100 images. True straight-alpha transparency.
AI Image Upscaler
2× and 4× super-resolution with automatic source routing — a real-world restoration model for compressed photos, edge-preserving scaling for logos and flat art, Swin2SR for clean photos.
GIF Background Remover
Transparent animated GIFs, frame by frame — instant colour-key for solid backgrounds, AI models for everything else. Dithered, de-haloed GIF alpha or full soft-edge APNG.
Photo Colorizer
Bring black-and-white photos to colour — four instant classical styles, or the DDColor AI model (optional one-time download) for photorealistic results.
AI Face Restore
Recover facial detail in small, soft or damaged photos with GFPGAN v1.4 (optional 340 MB download), or an instant classical pipeline. Old scans, group shots, low-light snaps.
AI Image Deblur
Sharpen camera shake and focus miss. A real NAFNet deconvolution (optional 92 MB download) reconstructs detail; a direction-aware unsharp mask runs instantly either way.
AI Alt Text
Generate alt text and image descriptions on your device for accessibility, listings and social captions. Needs a one-time ~120 MB model — there is no classical shortcut for this one.

Detect faces (~15 MB) or licence plates (~81 MB plus uncached shared runtime) only when requested, correct regions, then apply reviewed blur or pixelation to images or tracked video.

Score scenes by motion, visual prominence and speech energy, then review chronological 15, 30, or 60-second ranges before one audio-preserving timeline commit.
Video Upscaler
Upscale video with a classical denoise → Lanczos → sharpen enhancement pipeline (no AI — it cannot invent detail, and says so). Light, Balanced, and Strong presets.
Video Editor
Scene backgrounds behind transparent clips, in-editor background removal, object remover (click-to-select), colour grading, text overlays, layers, trim, export.
