Resize Image
Set a new pixel width or height for a JPG, PNG or WebP image and download it in its original format.
Open Resize ImageStep-by-step instructions
- Choose one JPG, PNG or WebP image.
- Enter a target Width or Height in pixels. Leave the other field blank to retain the original proportions.
- If you need an exact width and height, enter both and check that the proportions are appropriate.
- Run Resize Image, save the result and inspect its dimensions and appearance.
Supported files and result
The result is one image in the same JPG, PNG or WebP format as the source. Supported JPEG orientation is applied before dimensions are calculated. PNG and WebP transparency can be retained.
Dimensions and proportions
Entering only width calculates height automatically; entering only height calculates width automatically. Pixel dimensions are rounded to whole numbers.
Entering both values resizes the entire image to those dimensions. Different proportions can stretch or squash the picture. Use Crop Image first when you need to change the shape without stretching its content.
Enlarging an image creates more pixels but does not recover detail missing from the original. A smaller image is usually more useful for reducing upload or display size.
Limits and troubleshooting
At least one dimension is required. Each requested side must be between 1 and 8000 pixels, and the total pixel count must also fit the processor safety limit. Entering 8000 for both sides may therefore be rejected.
If the image looks distorted, repeat the export with only one dimension filled in. If the processor reports a memory or dimension limit, lower the requested dimensions or use a smaller source file.
Processing and privacy
The selected files are uploaded to Helphonic for processing in private storage. No third-party file-processing service is used. Temporary source and output files are removed after the download response, and failed processing cleans up temporary files. Keep your originals and save the result to your device.
Access and current limits
Check the tool page for current access, remaining usage and per-operation limits. File count, per-file size, total size and page limits can depend on your access and can change. Device and processor safety limits still apply when usage is unlimited. A paid pass does not necessarily increase every processing limit.
One successful export counts as one operation, including its multiple files or pages. Changing options and local previews do not use an operation. Current access checks must complete before the tool can release the result.
Check the current limits
Allowances and per-operation limits can change. The Resize Image page shows the policy that applies to you. Per-operation safety limits still apply when usage is unlimited. See access passes if a tool or extra usage requires paid access.
