DEX Mini szerző: vxkram

DEX Mini brings the DEX image tools to Firefox, with the same rule: lossless whenever possible, and it tells you plainly when it isn't.

Edit any image

• Right-click an image on a page and choose Edit with DEX…, or pick one from the toolbar button
• Crop to 1:1, 4:3, 3:4, 16:9, 9:16, or any custom ratio or exact pixel size
• Fit the whole image into a shape, with a blurred, coloured or transparent background around it
• Rotate, flip, and resize (75%, 50%, 25%, 4K, Web, Social)
• Convert to PNG, JPEG or WebP, and rename the file before saving

Animated GIFs

• A timeline with play/pause and trim handles
• Crop and resize every frame, then save as a GIF, or save the frame you're on as a PNG
• Frames keep their exact colours whenever they fit GIF's 256-colour limit

Know what you lose

Every export shows a verdict before you save: No re-encode, Lossless or Re-encode (lossy), with the reasons listed, such as:

JPEG encoding at quality 95

Transparency will be flattened onto white

When a lossless option exists, DEX offers it.

Convert downloads automatically (optional, off until you turn it on)

• WebP images arrive as PNG (lossless) or JPEG
• WebM video becomes MP4. By default the streams are copied untouched, with no re-encoding. You can choose H.264 instead, which plays everywhere
• Animated WebPs are left as they are, and if anything can't be converted you keep the original

Private by design

Everything happens inside your browser. DEX Mini doesn't upload, track or collect anything. It reads only the images you open and the downloads you ask it to convert.
