Upload the sideways photo
Use the original from your phone — not a screenshot, which loses quality.
File preparation assistant
Some portals ignore the rotation flag that phones store, so an upright photo appears sideways after upload. This tool bakes the correct rotation into the pixels themselves.
The photo is re-encoded without EXIF data, so GPS location, camera model and capture details do not travel with the file. Sideways phone photos are rotated upright first, so portals that ignore orientation metadata display them correctly.
Use the original from your phone — not a screenshot, which loses quality.
The stored orientation flag is applied to the actual pixels and the flag is then removed, along with other EXIF metadata.
Every website and viewer now shows the same upright image, because the rotation is real rather than a metadata hint.
Phones often save the sensor image unrotated plus a flag saying how to display it. Sites that ignore the flag show the raw sideways pixels.
If the photo was already saved without a flag (for example after editing), there is nothing to apply automatically. Use the resize tool's crop preview or rotate it in your gallery first.
One high-quality re-encode is performed. Rotation itself is lossless for right-angle turns.
