Common errors & troubleshooting
Browser slows down or tab crashes
Cause: Too many huge camera photos in one batch.
Fix: Process 20–50 images at a time, or downscale more aggressively before a second pass.
Images look cropped unexpectedly
Cause: Square / landscape / portrait modes use cover-crop by default.
Fix: Switch fit mode to contain (letterbox) if you need the full image without cropping.
ZIP download is empty
Cause: Batch failed before files were encoded.
Fix: Check the error message, remove unsupported files, and run Batch Resize again.
Privacy and security
- Your input and generated output are processed locally and are not sent to our servers for tool execution.
- Opening a local file uses the browser File API; the file is not uploaded to UtilityKit.
- We may collect anonymous product analytics (for example page views). Tool contents are not included in those events.
- Processing is limited by your device memory and CPU — this is intentional for privacy.
- Upscaling cannot invent true detail; it only interpolates existing pixels.
- EXIF/GPS metadata is removed when images are re-encoded through canvas (desired for strip-metadata mode).
- Animated GIF/WebP frames are flattened to a still frame in batch resize modes.
Frequently asked questions
How many images can I resize at once?
There is no hard server quota because processing is local. Practical limits depend on RAM — start with 20–50 large photos, or more for smaller web assets.
Is Batch Image Resizer free for commercial use?
Yes. You can use it for commercial projects. Files never leave your browser for the resize step.
Does batch resizing keep aspect ratio?
By default yes — width- or height-led modes preserve aspect ratio. Exact-dimension mode can stretch if you unlock aspect.
What formats are supported?
Common inputs include PNG, JPG, WebP, GIF, BMP, and HEIC (where the browser stack can decode). Export PNG, JPG, or WebP.
