Media AI Apps

Free passport, visa & ID photo maker. Crop to official size with head guides, then download a print-ready 4x6/A4 sheet for CVS, Walgreens, or any pharmacy kiosk. Runs fully in your browser - no upload, no watermark.

Private browser photo editor with a real on-device portrait AI cutout model, mouse-drag crop and cutout placement, film looks and offline support. Zero uploads.

Upload one reference image and get a procedural, animation-ready Three.js reconstruction rendered live in the browser: primitives, lathe profiles and PBR materials, exportable as spec JSON, as a createModel() factory module, or as one runnable self-contained .html file you can open by double-click. Derived from the open-source img2threejs skill by hoainho (github.com/hoainho/img2threejs, Apache-2.0).

Open and read PowerPoint (.pptx) presentations right in your browser. Completely free - no sign-in, no upload, no usage billing. High-fidelity slides, thumbnails, and a presenter mode; files never leave your device.

Turn a phrase into a full-screen typographic slide: double-click to edit, then tune text colour, gradient background and angle, font, weight, size, italic, uppercase and drop shadow. 'Save URL' encodes the whole design in the link so it reproduces exactly. Runs fully client-side. Imported Claude artifact. Source: https://github.com/simonw/tools (big-words.html, Apache-2.0).

Crop an image to the ratio the destination actually wants - 2:1 Twitter/LinkedIn, 1.91:1 Facebook, 1.4:1 Substack, 1:1 Instagram - with a background colour for the area the crop does not fill, so the platform does not re-crop through the part that mattered. Drop, paste or pick a file; it never leaves the browser, and no third-party CDN code is loaded. Imported Claude artifact. Source: https://github.com/simonw/tools (social-media-cropper.html, Apache-2.0).

Arrange photos into a printable grid - portrait or landscape, photos per row, rows per page, fit or fill - and print at actual size with a preview that matches the paper. The print stylesheet hides the controls automatically. Photos never leave the browser. Imported Claude artifact. Source: https://github.com/simonw/tools (image-print.html, Apache-2.0).

Drop an animated GIF and extract every frame with its real metadata - delay, disposal method, dimensions, offsets - rendered one by one. For pulling a still out of an animation, or working out what timings a GIF actually contains when it plays wrong somewhere. Decoded in your browser with no third-party CDN code; nothing is uploaded. Imported Claude artifact. Source: https://github.com/simonw/tools (gif-dissector.html, Apache-2.0).

Drop a JPEG and read its EXIF/TIFF orientation tag - the flag that decides whether a photo displays upright or sideways - with the raw value, its meaning, and debug detail like EXIF offset and file size. For settling which side of an upload pipeline is ignoring the tag. Parsed locally with DataView; the file is never uploaded. Imported Claude artifact. Source: https://github.com/simonw/tools (tiff-orientation.html, Apache-2.0).

Load a video, drag a crop box over the part you want to keep, and get the exact ffmpeg command - correct crop=w:h:x:y for the video's real pixel dimensions, plus an iPhone-compatible variant. The video loads locally as a blob for preview only; nothing is uploaded and no encoding happens in the browser. Imported Claude artifact. Source: https://github.com/simonw/tools (ffmpeg-crop.html, Apache-2.0).

Ask an AI image model to mark up a photo and it returns a subtly re-rendered image rather than your original. This isolates just the red annotations as a transparent PNG - with a sensitivity slider - and can composite them back onto your untouched original, so you get clean marks over pristine pixels. Runs fully client-side; neither image is uploaded. Imported Claude artifact. Source: https://github.com/simonw/tools (red-extractor.html, Apache-2.0).

Paste a vision model's segmentation output - objects with box_2d bounds and base64 masks - and see the boxes and masks drawn over the image, with a switchable co-ordinate origin for when a mask lands mirrored or rotated. Ships an embedded example so it demos without an upload. Runs fully client-side. Imported Claude artifact. Source: https://github.com/simonw/tools (mask-visualizer.html, Apache-2.0).

Type text, pick from the voices installed on your own machine, and hear it spoken - with rate, pitch and volume sliders and a stop control. Uses the browser's built-in speechSynthesis API, so audio is generated on your device and nothing is uploaded. Imported Claude artifact. Source: https://github.com/simonw/tools (speech-synthesis.html, Apache-2.0).

Turn any image into a custom Slack emoji: square, transparent background, PNG under 128KB. Four background-removal modes (edge flood, edge colour, connected region, colour-everywhere) with a tolerance slider, undo/redo and reset. Runs entirely in your browser - nothing is uploaded. Imported Claude artifact. Source: https://github.com/simonw/tools (slack-emoji-maker.html, Apache-2.0).

Open an image, click the colours you want removed, tune a tolerance slider to catch near-matching shades, and download a transparent PNG. Works with PNG, JPEG, GIF and WebP; drag, paste or pick a file. Fully offline in your browser - the image is never uploaded. Imported Claude artifact. Source: https://github.com/simonw/tools (transparent-png.html, Apache-2.0).

Resize, crop and re-encode images entirely in your browser, then compare quality settings and file sizes side by side. Nothing is uploaded — the image never leaves the page. Imported Claude artifact. Source: https://github.com/simonw/tools (image-resize-quality.html, Apache-2.0).
