One workflow for every marketplace image size

Import by drag-and-drop or file browser

Drop one or many supported images into the window, or browse to select files. Unsupported types are rejected clearly; corrupt files are surfaced with an error instead of failing silently.

Preview queue with file metadata

See a thumbnail, original filename, pixel dimensions, and file size for each queued image before you export—so you catch wrong files early.

Built-in presets for common seller surfaces

Purpose-driven defaults you can combine in one batch:

• Gumroad Cover — landscape product-cover style (16:9)
• Etsy Thumbnail — square, marketplace-friendly framing
• X (Twitter) Image — wide card suited for posts and previews
• Web Optimized — fit within a max box, WebP output, smaller files
• Custom — your own width, height, fit, format, quality, and pad color

Formats & quality controls

Export to PNG, JPEG, or WebP with per-preset quality. JPEG uses mozjpeg-oriented settings; PNG uses strong compression; WebP targets efficient delivery for your own site or handoff.

Resize modes that match real design work

Choose contain, cover, fill, inside, or outside to match how you want aspect ratio handled. Optional background color (hex) pads letterboxed areas when the fit mode introduces empty space.

Batch export to a folder you control

Pick an output directory (the app remembers the last one). Export all combinations of selected images × selected presets in one run, with automatic filename collision handling when two outputs would share the same name.

Flexible output naming

Choose how files are named on disk:

• Original filename (extension follows the export format)
• Original name plus preset suffix
• Custom prefix or suffix around the original stem

Text and image watermarks

Add a text watermark with position (corners or center), opacity, size relative to the image, margin, and color. Optionally apply an image watermark (e.g. logo) with scale and opacity—useful for branded previews or subtle protection.

Progress, outcomes, and a final summary

During export, see per-item status as each image and preset completes. When finished, review a summary: how many files exported, which combinations failed (with reasons), and the output folder path—then open the folder in Explorer from the app context when supported.

Privacy-first, offline architecture

No in-app accounts, cloud sync, or analytics SDKs. Image transforms run through Sharp on your machine. Preferences (last folder, selected presets, naming, watermark defaults) are stored locally—ideal when you work with licensed or confidential client assets.

Windows distribution

Built for Windows 10 and 11 (x64), distributed as a standard installer so end users can install and uninstall like any other desktop program. The public site is hosted at seller-image-exporter.netlify.app.
