Does flipping a PNG reduce image quality?

No. PNG is a lossless format and flipping is a pure pixel rearrangement — no resampling, no recompression of the kept pixels, no quality loss. The output PNG is bit-identical to the source apart from the mirrored layout. You can flip the same file dozens of times with zero degradation, unlike JPEG which loses a small amount of quality on every re-save.

Will the transparent background survive the flip?

Yes. PNG's alpha channel (transparency) is preserved exactly during a flip — every transparent pixel stays transparent in the output, and partial transparency (anti-aliased logo edges, drop shadows, soft masks) is kept pixel-perfect. This is the main practical advantage of flipping a PNG over flipping a JPG, which would have flattened transparency to white before you ever started.

What's the difference between "flip" and "mirror"?

They're the same operation. "Mirror" usually refers to a horizontal flip (reflecting left ↔ right, like looking in a bathroom mirror), which is also what most apps mean by "Flip Horizontal". "Flip Vertical" is the top ↔ bottom version. If a tool labels its single button "Mirror", it almost always means horizontal — pick "Vertical Flip" here for the upside-down version.

Why does my selfie look mirrored, and will flipping fix it?

iPhone and most Android phones display the front camera preview mirrored so it feels natural while you're framing the shot, but they save the file un-mirrored — which is why text on your shirt reads correctly in the saved photo but feels "wrong" if you were used to the preview. A horizontal flip applied here recreates the mirrored preview view, which is what you actually want when posting to social media.

Can I batch flip many PNG screenshots in the same direction?

Yes. Drop in multiple PNGs and pick a flip direction once — every file processes in parallel with the same horizontal or vertical setting. Useful for flipping a folder of screen recordings (which webcam software preview-mirrors), reversing a sprite sheet for a game character facing the other way, or mirroring a batch of iconography for an RTL localization. Files download individually or as a single ZIP archive.

Will flipping change the file size?

Almost identically the same size. The pixel data is the same — just rearranged — so the PNG encoder produces a file within a percent or two of the original. PNG uses DEFLATE compression which is sensitive to byte order, so a flipped image can occasionally encode a few KB smaller or larger depending on horizontal-line redundancy. If you need the file smaller after flipping, lower the Compression Level or downscale the resolution in step 3.

Can I rotate and flip in one step?

Not in a single click here, but you can flip the PNG, download it, and then run Rotate PNG on the result. A horizontal flip plus a vertical flip is the same visual outcome as rotating 180°, so if that's what you actually want, use the rotate tool directly with a 180° preset. For 90° / 270° turns, rotate is the right tool — flipping doesn't produce those orientations.

Will flipping work on text inside a PNG screenshot?

Technically yes — but the text in the output will be mirror-readable (backwards). PNG flipping operates on pixels, not glyphs, so any rendered text inside a screenshot will be reversed left-to-right (horizontal flip) or upside down (vertical flip). If you want the image flipped while text stays readable, that's a manual edit in Photoshop / GIMP / Photopea where you flip the background layer and re-render the text on top.

Does flipping a PNG work on other image formats too?

Yes — see Flip JPG, Flip GIF, Flip WebP, Flip BMP, Flip TIFF, and Flip HEIC for the same flip controls applied to the equivalent formats. JPG flipping does involve a re-encode (JPG is lossy), but the quality loss from a single flip is invisible at default settings.
