Resize images in your browser.
Resize one image or a batch by exact pixels, percentage, or a maximum bounding box. Apply one setup to all images or switch to per-image overrides, preview the result, then download one file or a ZIP.

Large upscales can soften source detail. Keep originals when image quality matters and inspect the preview before downloading.
Pixels, percentage, or fit-to-box
Resize a whole batch without repeating the same setup.
Choose exact dimensions, scale by percentage, or fit each source inside a maximum box. Shared mode is fast for a batch; individual mode handles exceptions without starting over.
Private by design
Source images are decoded and processed locally in your browser. No image-processing API upload is required for this tool.
- Resize JPG, PNG and WebP images locally.
- Use exact pixels, percentage scaling, or fit-to-box.
- Lock width and height to the active image aspect ratio.
- Preview the active image before running the full batch.
- Download one result directly or multiple results as a ZIP.
How to use it
How to resize images online in a browser.
Choose a sizing method that matches the job, check the active preview, then process the batch locally without uploading source images to a resize API.
Add JPG, PNG or WebP images
Choose one image or a batch. The queue keeps the files together while you review and edit the active image.
Choose pixels, percentage or fit-to-box
Use exact dimensions for a fixed output size, percentage for proportional scaling, or fit-to-box when every image must stay inside a maximum width and height.
Keep the aspect ratio when needed
With aspect lock enabled, each image keeps its own proportions instead of inheriting the shape of another image in the batch.
Preview, resize and download
Inspect the active preview, process the batch sequentially in your browser, then download one result or a ZIP of multiple results.
When to use it
Use the resize tool for web images, thumbnails and batch dimension cleanup.
Resizing changes pixel dimensions, so the best method depends on whether you care about exact size, relative scale or a maximum bounding box.
Batch or individual
Use Apply to all when the same setup fits the batch. Switch to Edit individually when one image needs different settings without rebuilding the rest of the queue.
- Create consistent maximum dimensions for website and blog images.
- Scale a batch down by the same percentage while preserving each source aspect ratio.
- Prepare smaller copies before compression or sharing.
- Resize mixed portrait and landscape images without forcing them into one shape.
FAQ
Resize Image FAQ
Practical answers about resize image, local processing, batch behavior and output limitations.
Can I resize multiple images at once?
Yes. Add up to the tool batch limit, use Apply to all for one shared setup, or switch to Edit individually when a specific image needs different dimensions.
Will Lock aspect ratio stretch portrait and landscape images?
No. The resize logic preserves the aspect ratio of each individual source image. A mixed batch does not reuse the active image ratio for every file.
Does resizing improve image quality?
No. Reducing dimensions can make a file easier to use, but enlarging an image cannot recreate detail that was not present in the source. Large upscales can look softer.
Are my images uploaded to a server?
The resize workflow decodes, previews, processes and encodes supported images in the browser. Source images are not sent to an image-resize API.
