PNG → JPG
Flatten PNG to JPEG for photos and documents that do not need transparency. Configurable fill, all local.
Real privacy: your images never leave your device.
If the image has transparency (e.g. a PNG), choose whether to keep it or fill it with a solid color.
JPG does not support transparency: it will be filled with the chosen color.
PNG is excellent for sharp graphics and alpha, but photos casually exported as PNG often weigh more than needed. JPEG compresses photographic scenes better. If the destination is email, a legacy CMS, or a form that only accepts JPG, this conversion avoids rejections.
SMALLIMG preselects JPG and makes you decide what happens to transparent areas—the detail people trip over in generic PNG-to-JPEG tools.
If the PNG is an opaque photo, fill barely matters. For a cutout, choose white for documents, black for dark decks, or your brand hex. You can still keep alpha by switching output to PNG or WebP, though this page is oriented to JPG.
For catalogs, unify the background (for example white) across the batch before uploading to the store—avoid gray frames inherited from the editor.
Tune quality and, if needed, max width. A 300 DPI capture PNG can drop resolution for the web without losing usefulness. Watch small text: aggressive JPEG softens UI.
As with the rest of SMALLIMG, the file is not sent to our servers. That fits when the PNG is an ID scan, a contract, or unpublished art—cases where a “free” upload is a bad deal.
No. JPG has no alpha channel. Use fill or switch output to PNG/WebP.
At high quality, photos usually look very close. On text-heavy graphics, watch for artifacts.
The browser decodes what its image engine supports. If a PNG fails, re-export from your editor.
You can add several images; the practical limit is your device memory.
You're on the list.
