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 any pharmacy photo kiosk or photo shop. Runs fully in your browser - no upload, no watermark.

A fart sound generator that is a real synthesiser: nothing is played back from a recording. Every parp is computed in your browser from eight controls — length, pitch, tightness, wetness, burstiness, glide, room and grit — across two engines, one a pulse train and one a flapping-membrane model whose pitch is a result rather than a setting. Randomise it, save the good ones, download a WAV, or share a 27-character link that reproduces the exact same noise. Free, no model, no credits, no sign-in.

Blend two photos into one picture. Upload two images, choose what survives and what is borrowed — palette and light, style and medium, material, setting, a merged subject or a double exposure — then read and edit the render brief before you spend anything. Photographs are resized in your browser and stripped of location data before upload. Face swaps and pictures of real people doing things they did not do are refused.

Generate photorealistic portraits of entirely fictional people, steered by broad attributes: age range, presentation, lighting, framing, lens, era, mood and treatment. Placeholder avatars, character references and mock-up faces with no real person behind them. Requests for the likeness of a real individual are refused, not attempted.

An impossible creature generator that checks its own anatomy. Combine real animals into a hybrid, or specify a creature — habitat, mass, diet, locomotion, body covering, thermal strategy — and twenty-one deterministic rules test whether it could actually live: wing loading against mass, exoskeleton mass fraction, fermentation gut volume, surface-to-volume against habitat temperature. Then it renders the result as a naturalist's plate. The composer, the coherence report and the content guard all run in your browser before you spend anything.

An anime art generator you can steer. Describe a character or a scene, choose a drawing register — cel-shaded, watercolour, retro 90s OVA, modern digital, chibi, black-and-white manga or soft pastel — then set linework, shading, palette, framing, composition, lighting and mood. Read the exact brief before you spend anything. Original invented designs only: suggestive content and likenesses of real people are refused in the browser, before any credit is reserved.

Give it a subject, a mood, a genre and a song structure and get an original lyric back - verses, chorus, bridge - with the working shown: the rhyme scheme derived from the actual line endings, a syllable count for every line, which line is the hook and where it lands, and what the bridge is doing that the verses are not. Every line is checked in your browser before you see it against an index of well-known song titles and one-way fingerprints of well-known hooks, and against detectors for output that presents words as somebody else's. The app never reproduces an existing song's words and never puts words behind a real artist's name. It also says plainly what its check can and cannot see, with the measured numbers.

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.

A surreal image generator you can actually steer. Choose the kind of strangeness — scale inversion, material substitution, physics violation, uncanny recombination, repetition, wrong place, inside out, absence, time out of joint, animacy swap — and the medium that carries it: oil painting, photographic realism, cut-paper collage, etched illustration and seven more. The brief is composed in your browser and shown in full before you spend anything. Invented scenes only; likenesses of real people and gore are refused before any credit is reserved.

Give it a genre, a mood and optionally a couple of reference acts, and get band names that would plausibly appear on a poster for that scene — with, for each one, which naming convention it uses, how it behaves as a wordmark on a shirt or a spine, and whether it is likely already taken. Every name is checked in your browser against a corpus of well-known acts before you see it: exact matches, matches that differ only in punctuation or a leading The, and near-misses. A clear result means the name is not in our list, which is not the same as available, and the app says so.

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.

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).

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).

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).

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).

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).

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).

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).

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).

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).

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).

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).

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).

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).
