How to straighten a scanned image
- 01
Open the scan
Upload one supported image up to 50 MB and select the frame you need.
- 02
Level the text
Review the detected angle. Adjust the slider, degree field or fine rotation buttons.
- 03
Save the correction
Choose a format, click Deskew Image and download the straightened copy.
Straighten tilted text without cropping the corners
Deskew Image rotates a scanned page or photograph to make its text lines more level. A detected angle provides a starting point, while the manual controls let you correct or replace that suggestion.

Features and controls
Start with the detected correction
The tool suggests a small rotation based on the image. Use detected angle restores that suggestion after manual changes.
When to trust the suggested angle
Compare several lines of ordinary text rather than a single heading. If the text now looks level, the suggestion is a useful starting point. If it looks worse, use a manual value or return to zero.
Detection works best when the image contains a consistent direction. Sparse text, diagrams, ruled forms and mixed orientations can produce an unhelpful angle. It is not a guarantee that the page is correctly aligned.
Fine-tune the rotation in degrees
Adjust the slider or enter an angle from -45 to +45 degrees. The fine controls change it in 0.1-degree steps.
Direction and manual adjustment
Positive angles rotate clockwise and negative angles rotate counterclockwise. Make small changes and compare the text with the horizontal edges of the preview.
Use Rotate Image for a sideways or upside-down page. Deskew is intended for tilted content, and it does not correct a trapezoid caused by photographing a page from one side.
Review the expanded canvas
The output expands around the rotated image to keep its corners. Border areas depend on the source and output format.
Borders, transparency and further cropping
An image with transparency can keep transparent corners in PNG or WebP. An opaque source uses white padding; JPEG also replaces transparency with white.
A non-right-angle rotation resamples pixels and can soften fine detail. Inspect small text and crop the extra border afterward if needed, without trimming the useful characters.
Choose one frame or page
Open a still image or choose a frame from a supported animated or multipage source. Only that selected frame is exported.
Supported files and frame scope
PNG, JPG, JPEG, TIF, TIFF, BMP, GIF, WebP and HEIC are supported inputs. Open one file up to 50 MB. Files may contain up to 100 frames or pages; image dimensions and decoding limits also apply.
Frame navigation changes the image being edited. Saving a result does not preserve a whole animation, its timing or all pages of a multipage file. Choose each required frame separately.
Choose PNG, JPEG or lossless WebP
PNG is the default. PNG and WebP can keep transparency; JPEG uses a white background for transparent pixels.
Output quality and source preservation
PNG and lossless WebP avoid lossy encoding. JPEG is saved at its highest quality setting, but it is still a lossy format; it is not a lossless copy of the source.
The output is a new image. The original file stays unchanged, but the export does not preserve all original metadata or every source-format feature. Use a separate source copy when those details matter.
Supported files & processing
- Input
- PNG, JPG, JPEG, TIF, TIFF, BMP, GIF, WEBP, HEIC
- Output
- PNG, JPEG, WebP
Open one supported image up to 50 MB, with no more than 100 frames or pages. Pixel dimensions and decoding limits also apply. Each run exports only the selected frame as a still image.
Your image uploads to our servers to prepare its preview and process the selected frame. These tools do not run OCR. Download the result you need and keep the original separately; see the Privacy Policy for file handling details.

FAQ
Before you start
Formats, selected frames and output quality explained.
Server processingDoes Deskew Image always find the correct angle?
No. The detected correction is a starting point. Check several text lines and adjust the angle yourself when a heading, diagram or unusual layout gives a misleading result.
Will it straighten a page photographed from the side?
It can correct rotation, but not perspective distortion, curved pages or warped lines. A new photograph taken parallel to the page may be more useful.
Why are there extra corners after deskewing?
The canvas expands so the rotated image is not clipped. Newly exposed areas are white for an opaque source or transparent for a transparent source when using PNG or WebP.
Which files and sizes can I use?
Open one PNG, JPG, JPEG, TIF, TIFF, BMP, GIF, WebP or HEIC image up to 50 MB. Files may contain up to 100 frames or pages, with additional pixel and decoding limits. Only the selected frame is saved as a still image.
Which download format should I choose?
PNG is the default and uses lossless encoding. Lossless WebP also preserves image detail and transparency. JPEG is saved at its highest quality setting but remains lossy, with white replacing transparent areas. The export is a new image, not an unchanged copy of the original file and its metadata.
Does this run OCR or change my original?
No OCR runs in this image tool. The file uploads for preview preparation and image processing, and the result is a separate image. You can continue to Image OCR when you need text; that tool has its own limits and verification.
