Image flipper — flip image online

Free image flipper: flip image or photo online—mirror horizontally or vertically. Preview and PNG download in browser, no upload.

What is a mirror PNG / image flipper?

Mirroring an image (mirror PNG, mirror an image, mirrored image, mirror image online, photo mirror, reverse mirror online, image mirrorer) reflects pixels along a horizontal or vertical axis — the same geometry as an image flip. Horizontal mirror swaps left and right; vertical mirror swaps top and bottom. Searches like image flipper, flip picture, and flip image online describe the same tool. Uwarp runs the mirror in your browser so you can flip or mirror a PNG, picture, or photo locally, preview next to the original, and download without uploading files to a server. Color inversion is different — use /invert-image-colors for that.

Mirror PNG & image flipper features

Mirror image online—flip PNG horizontally, vertically, or both.

  • Horizontal & vertical mirror

    Mirror PNG left-right for reversed shots; vertical flip for upside-down photos; both for a 180° effect.

  • Image mirrorer online

    Free mirror image / photo mirror / reverse mirror workflow—no account, no upload to a server.

  • Side-by-side preview

    Compare original and mirrored image before you download.

  • Transparent PNG support

    Mirror PNG uploads keep alpha. JPEG and WebP also work; exports are PNG from the canvas.

  • PNG download

    Save the mirrored result. For color negative, use /invert-image-colors instead.

How to flip an image

Steps that match flip photo, flip picture, and mirror picture online searches.

  1. Upload the image

    Drop or click in the input panel (15 MB maximum).

  2. Choose mirror direction

    Flip image horizontally for left-right mirror, vertically for upside-down fixes, or both.

  3. Download the flipped PNG

    Save when the preview looks correct.

Tips for flip image and mirror workflows

Get the axis right before download.
  • 01

    Start with horizontal for mirror selfies

    Most “image mirror” fixes are flip image horizontally only.

  • 02

    Use vertical for upside down shots

    Vertical flip is the usual fix when the sky appears at the bottom.

  • 03

    Both axes for 180°

    Horizontal plus vertical equals a half-turn without changing width and height.

  • 04

    Flip PNG to keep transparency

    JPEG works but exports with a solid background from the canvas encoder.

  • 05

    Do not confuse flip and invert

    Invert pic or invert photo searches often want color negative—use /invert-image-colors.

  • 06

    Re-upload for a new file

    Replace the input image instead of flipping the same download repeatedly.

Mirror / flip image tools compared

How this free mirror PNG and image flipper stacks up against other online options.

  • Online PNG Tools (mirror PNG)

    Competitor ranking for mirror PNG, mirror an image, and mirror image online. This page matches that intent with horizontal/vertical mirror, live preview, and transparent PNG download.

  • Online PNG Tools (flip PNG horizontally)

    Same geometry as horizontal mirror. This tool covers both flip and mirror wording in one place.

  • PineTools / ImageOnline / ILoveIMG

    Common flip/mirror utilities with upload flows. This page keeps processing private in the browser with side-by-side preview.

  • This mirror / flip tool (/flip-image)

    Free image mirrorer: mirror PNG, photo mirror, reverse mirror online — horizontal, vertical, or both.

When to use an image flipper

Common flip image and image mirror tasks.

  • Mirror selfies and scans

    Flip photo horizontally when the camera saved a reversed shot.

  • Upside down images

    Vertical flip corrects photos that imported inverted.

  • Logo and UI direction

    Mirror image assets for layout experiments and RTL previews.

  • Pattern and texture checks

    See if tiles still align after an image flip.

  • Social and slide graphics

    Quick flip picture online before export to decks or feeds.

  • After flip, invert colors

    Need a color negative? Open /invert-image-colors after you mirror geometry here.

Why use this image flipper online

Benefits over one-off desktop mirror tools.

  • Private image flip

    Pixels are not sent to Uwarp servers during mirror or flip.

  • Instant preview

    Toggle axes and see the image flip immediately.

  • No install

    Works as image flipper online from any modern browser.

  • Free

    Unlimited flips and PNG downloads.

  • Clear horizontal vs vertical labels

    Options spell out left-right versus top-bottom mirror.

  • Uwarp image toolkit

    Same limits and export pattern as /invert-image-colors and /imagetracer.
