Roter bilde

Roter bilde. Rotate and mirror batches of still JPG, PNG and WebP images locally. Use custom angles, compare outputs and download individual images or a ZIP. Rotate or mirror batches of still JPEG, PNG and WebP images on your device.

Choose 90°, 180°, 270°, −90° or a custom angle between −360 and 360 degrees, including decimals. Positive angles turn clockwise; flips act in the source image’s frame before rotation. Settings apply to every queued image.

Select Same as input, JPEG, PNG or WebP output. Each source and output is limited to 20 MiB. Up to 10 files may be selected, with separate 50 MiB input and completed-output budgets.

Both source and expanded output must fit 24 megapixels and 8,192 pixels per edge. Processing stops after 30 seconds per file. GIF, SVG, AVIF, HEIC, animated PNG and animated WebP are unsupported.

If a supported source expands beyond the output limit, reduce its dimensions with Image Compressor before rotating. Sources that already exceed the input limits need resizing in another image editor.

The canvas expands and rounds outward so custom-angle bounds do not clip source edges. A 120 × 80 image at 90° becomes 80 × 120; at 45° its canvas becomes 142 × 142. PNG and WebP preserve transparent corners; JPEG uses white corners.

Browser orientation is applied before your transformation. Results are re-encoded at quality 100, which does not guarantee lossless JPEG/WebP. File size, colors and profiles may change; source EXIF is not copied.

Images are processed in memory without upload or browser storage; ads make separate network requests.

Ofte stilte spørsmål

How do I rotate an image?

Choose up to 10 still JPG, PNG or WebP files, set an angle from −360 to 360 degrees and optional flips, then rotate. Positive angles turn clockwise. Compare results and download individual images or a ZIP.

Which direction do rotation and flips use?

Enter −360 to 360 degrees, including decimals. Positive rotates clockwise; negative rotates counterclockwise. Flips apply in the original image’s frame before rotation. These settings apply to every queued image.

Why does a custom angle change the dimensions?

The canvas expands to contain the rotated image and rounds its dimensions outward. Quarter turns swap width and height exactly. For example, 120 × 80 at 90° becomes 80 × 120, while 45° becomes 142 × 142.

What color are the empty corners?

PNG and WebP keep transparent corners. JPEG cannot store transparency, so empty corners and transparent source areas become white.

Will rotation preserve quality and metadata?

Results are re-encoded even at 0°. The highest browser quality setting does not guarantee lossless JPEG/WebP. Colors, profiles and file size can change. Source EXIF is not copied; browser orientation is applied before rotation.

What are the supported formats and limits?

Only still JPEG, PNG and WebP. Up to 10 files, 20 MiB per file/output, separate 50 MiB input/output budgets, 24 megapixels and 8,192 pixels per edge for source and result. Animated images and other formats are rejected. Each file has a 30-second deadline.

Are images uploaded?

Images are processed locally without uploading them or saving them in browser storage. Ads make separate network requests. Clear the queue or leave this page to release the results.

Slik bruker du dette nettverktøyet

Roter bilde er laget for raske arbeidsflyter i nettleseren når du må formatere, validere, konvertere, dekode, kode, generere eller kontrollere data uten å åpne en tung skrivebordsapp. Start med inndatafeltet eller de synlige valgene, kontroller resultatet og kopier eller last ned utdataene.

Privat behandling i nettleseren

Roter bilde holder den vanlige behandlingen lokalt i nettleseren. Det er nyttig for kodebiter, tokens, dokumenter, konfigurasjonsverdier, tekstutdrag og annet innhold som ikke bør sendes til en ekstern tjeneste uten behov.

Når verktøyet er nyttig

Bruk Roter bilde til repeterbare utvikleroppgaver, teknisk dokumentasjon, QA-kontroller, raske konverteringer, feilsøking, innholdsrydding og interne teamflyter. Siden fokuserer på tydelige inndata, rask tilbakemelding og utdata som er enkle å bruke videre.

Praktiske tips

Før du kopierer sluttresultatet, bør du sjekke detaljer som mellomrom, store og små bokstaver, filnavn, koding, tokenstruktur, linjeskift eller utdataformat. Små kontroller hindrer feil når resultatet brukes i kode, rapporter, saker, e-post eller tekniske notater.
