Imging – Local Image Tools

PNG-8, WebP, JPG and AVIF

Palette refinement, multi-level alpha, optional dithering and quality controls. The 45.8 dB PNG-8 number is a single regression reference—not a universal promise.

Any image. One step to the result you need.

From compression and conversion to online design, AI cutout, animation creation and frame editing, ImgIng puts a complete workflow in the browser. Multi-layer layout, background setup and full-size export stay local; only a few formats the browser truly cannot handle use a server. JPG, PNG, WebP, GIF and APNG use your device directly; AVIF writing and HEIC reading stay local after on-demand WASM .

Use PNG-8, local AI mask refinement and a multi-layer canvas with move, scale, background, undo and full-size local export. Compress, create and edit GIF, APNG, animated WebP and animated AVIF; specialist formats have a clearly labelled server fallback.

Specialist server formats are paid features · admin@datadance.com

One image · Up to 40 MB

Instant = Browser can read the source and encode the target → processed locally, with no upload · Local WASM ↓ = WASM loads once (AVIF write / HEIC read), then processing remains local · Server = Only formats unavailable to the browser and local WASM (such as HEIC write) use a server

Same-format compression:Input and output formats stay the same · Up to 40 MB

Compress GIF / APNG directly · or select images to animate

Formats are grouped by where they run: common formats stay in your browser, while specialist and legacy formats use a clearly labelled server path.

Outlined chips (HEIC read and AVIF write) download libheif / libavif only when first needed, then continue entirely on-device. Animated AVIF* uses the ImgIng WebCodecs AV1 delta-frame path with no alpha and infinite looping; unsupported browsers fall back to the server. Total input coverage: 7 + 9 = 16 formats; local outputs: 8 formats (4 still + 4 animated).

GIF, APNG, animated WebP and animated AVIF can all be produced on-device when supported. Compare quality, size and compatibility before choosing.

Still images, multi-layer design, animation and AI share one local-first engine, with processing boundaries stated before you start.

Palette refinement, multi-level alpha, optional dithering and quality controls. The 45.8 dB PNG-8 number is a single regression reference—not a universal promise.

Import up to 24 images, move, scale and reorder layers, set the canvas background, undo changes and export at full size without up assets. Three local AI tiers preserve full alpha. Use a true 1 px brush, then set a colour or local background image and arrange the subject without up pixels.

Preserve original timing and loops, reorder or delete frames, change duration and bundle GIF, APNG and WebP outputs.

ImgIng attempts actual decode and encode paths instead of inferring support from a browser name alone.

Zoom, pan and drag the fixed divider, then decode the real exported Blob to verify the file you will download.

No single product wins every job. This table states where ImgIng fits and where another tool may be stronger.

Squoosh remains excellent for one-image codec experimentation. TinyPNG offers a mature cloud API ecosystem. Cloud converters cover more document and legacy formats. ImgIng focuses on local-first stills, animation, HEIC / AVIF and local AI in one workflow.

ImgIng tests whether your current device can really decode the input and encode the requested output. Unsupported paths are labelled before processing.

*** Full self-hosted build:** codecs load on demand and execute locally. Current Chrome or Edge is recommended for the broadest animation decode, WebGPU and WebCodecs support.

Each guide documents real settings, processing location, useful defaults and current limitations.

Decode iPhone photos locally and export broadly supported formats.

Tune palette, dithering and multi-level transparency for graphics and UI assets.

Preserve timing, edit frames and export several animation formats.

Refine full alpha, set a colour or image background, then move and scale the subject locally.

Arrange multiple image layers with canvas presets, backgrounds and full-size local export.

Choose RVM or aspect-aware MatAnyone2, replace the background, retain audio and export locally in desktop Chrome or Edge.

Separate source-image upload, WASM delivery, AI model caching and clearly labelled server-only formats.

Evaluate size, quality, transparency and compatibility together.

Compare privacy, animation, codecs and AI without inflated rankings.

Visible answers match the page’s structured data and current product behaviour.

Common formats—including JPG, PNG, WebP, GIF and APNG—and local AI cutout run in the browser. Only clearly labelled specialist formats use a server.

Device-side conversion, compression, animation and AI cutout are free, require no signup and add no watermark.

ImgIng reads PNG, JPEG, WebP, GIF, BMP, AVIF, HEIC and more, and exports still images plus GIF, APNG, animated WebP and animated AVIF.

The model must reach your browser before local inference can run. It is cached where possible and uses WebGPU first, falling back to WASM. Image pixels stay on-device.

Yes in the full build: libheif and libavif WASM load on demand, then run locally. HEIC writing remains a specialist server capability.

Squoosh excels at local still-image codecs; TinyPNG offers cloud compression and APIs. ImgIng integrates local-first stills, animation, HEIC / AVIF and local AI in one interface.

Choose a file, tune the result and download—without creating an account.

Drop or select one or many files, including HEIC, AVIF and animation.

Set format, quality, dimensions, palette, timing or AI model as needed.

Inspect size and detail, then save the real encoded result locally.

Device-side tools are free, require no signup and add no watermark.
