AI-generated Resize one image with padding, centered cropping, or stretching, then export PNG, JPEG, or WebP.

Screenshots supplied by the seller.

Description

AI generated by Codex for Shai. A local single-image resizer with exact output dimensions, contain/cover/stretch modes, transparency or background fill, quality controls, real encoded-size feedback, and downloadable PNG/JPEG/WebP output. Includes an original geometric sample.

The hosted demo works in memory only because its sandbox disables storage. Export a JSON backup to retain edits across reloads. The delivered source supports browser-local persistence on a regular static host.

Buyer receives editable source, core tests, documentation, and deployment setup. Private source handover is arranged by the seller; no hosting account or ongoing support is included.

Condition

Development stage: Working prototype (seller-declared)

Seller-declared: provided by the seller, not independently verified by SellMyVibe.

  • Solo creator
  • Mainly AI-generated
  • Under one month in development
  • Tests included
  • Setup guide included
  • Demo available

What works

  • Open a local PNG, JPEG, or WebP up to 15 MB and 40 million decoded pixels
  • Resize to exact dimensions with contain, centered cover, or stretch geometry
  • Choose transparent padding or a background color; JPEG always fills the background
  • Export a new image and see its actual encoded file size
  • Save and restore settings only; original image stays in tab memory
  • JSON backup/import; hosted demo works in memory without network requests

What’s unfinished

  • Single image only; no animation, batch processing, crop positioning, metadata preservation, or color-profile controls
  • Maximum output is 4,096 pixels per side and 12 million pixels total
  • WebP export depends on browser encoder support; unsupported export formats are reported
  • Image files are never stored in settings backups or browser storage; reopen after reload

Included assets

Full source code

Documentation

Deployment setup

Test suite

Technologies

HTML5, CSS3, Vanilla JavaScript ES modules, Browser localStorage (standalone source only)

Setup requirements

Unzip source and run python3 -m http.server 8080 in the folder. Open http://localhost:8080 or deploy to a static HTTPS host. No build or API key. Node 20+ runs test.mjs. See README.md and QA.md.

Dependencies and ongoing costs

No third-party libraries, APIs, backend, external fonts, images, or paid subscriptions. Hosted demo is served by SellMyVibe. Standalone source requires a static HTTP/HTTPS host, which may be free within provider limits; paid plans, overages, and custom domains may cost extra.

Known limitations

Working prototype. Single image only; no animation, batch processing, crop positioning, metadata preservation, or color-profile controls. Maximum output is 4,096 pixels per side and 12 million pixels total. WebP export depends on browser encoder support; unsupported export formats are reported. Image files are never stored in settings backups or browser storage; reopen after reload. App data resets on reload in the hosted demo; export JSON backups. See the app description for standalone storage behavior. No independent security audit or broad device/browser certification.
