Mirror (Flip) Image Online
Processing entirely on your device — large files may take a moment.
A horizontal flip mirrors the image left-to-right; a vertical flip turns it upside down. Both keep the original pixel dimensions.
Handy for fixing mirrored selfies, preparing print artwork or creating symmetrical designs from one half of a picture.

About the JPG format
JPG (short for JPEG, the Joint Photographic Experts Group committee that standardized it in 1992) has been the default photo format for over three decades. It compresses photographs using the discrete cosine transform: the image is split into 8×8 blocks, and details the human eye is bad at noticing are discarded. The result is files many times smaller than uncompressed data, at a quality level you control when saving.
In practice JPG is unbeatable for photographs and smooth gradients — camera memory cards, messaging apps and the web all assume it. It is a poor fit for screenshots, logos or anything with sharp edges and flat color, where compression leaves visible ringing around text. There is no transparency support, color depth is capped at 8 bits per channel, and every re-save with compression compounds tiny generational losses.
+ Strengths
- ✓Opens on literally every device, app and browser made in the last 30 years
- ✓Compresses photos dramatically — typically 10:1 or better with little visible loss
- ✓Quality level is adjustable, so you can trade fidelity for file size
- ✓Mature ecosystem: EXIF metadata, ICC profiles and progressive loading all supported
! Limitations
- −Lossy — artifacts appear on text, sharp edges and flat areas
- −No transparency, so overlays and logos need PNG or WebP instead
- −Repeated re-saving at low quality permanently degrades the image
Frequently asked questions
Does flipping change the file size?
Only through re-encoding. PNG stays lossless, JPG follows the quality slider.
Can I flip and resize in one step?
Not yet — run the image through this page first, then use the resize page with the result.
