Hi Product Hunt! I built MergeImage because combining a few screenshots or product photos should not require uploading the originals to someone else’s server.
The whole processing loop runs in the browser: add up to 30 images, reorder or transform them, choose horizontal, vertical, grid, or smart-stitch layout, preview, and export PNG, JPEG, or WebP.
The smart-stitch mode is deliberately conservative. It trims a repeated screenshot region only when the match is confident; otherwise it keeps the complete images instead of risking silent content loss.
I’d especially value feedback on mobile use, long screenshots, and mixed-size image sets. Thanks for taking a look!
Local processing for image merging is the version I'd trust, since the files people batch together are usually the ones they'd rather not upload — scans, screenshots with account details in them, documents.
Where does the 30 limit come from? Browser memory, or a deliberate cap to keep it responsive? I ask because 30 is oddly specific, and if it's a memory ceiling then image size probably matters more than count — 30 phone photos and 30 scans are very different asks.
