Resize WebP Images
Resize WebP images with a quality slider. Keep modern-format efficiency while hitting your target dimensions.
About the Resize WebP
WebP assets already on your site sometimes need dimension tweaks for new layouts. This tool re-encodes WebP at your chosen width and quality, keeping the format advantage without round-tripping through other formats.
How it works
The tool decodes WebP through the browser's native codec, scales it with stepped resampling, and re-encodes as WebP at your chosen quality. Staying inside the same modern codec means the file keeps most of its size advantage over JPG even after the resize.
How to use it
Add up to 10 .webp files, set the target width (aspect lock keeps proportions), pick a quality level — 80+ is usually visually identical — and process. Results show new dimensions and byte sizes before you download.
Supported formats & limitations
Input: .webp only (animated files use the first frame), 30MB max each, 10 per batch; output is .webp. Each pass is a new lossy generation, so archive originals if you expect to resize repeatedly.
Common use cases
Web developers adjusting assets inside WebP-first pipelines, designers iterating on page mockups, and anyone whose CMS exports WebP but whose layout needs it smaller. Pairs naturally with the web optimizer for a one-two publish step.
Frequently asked questions
How private is Resize WebP?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
What kind of image files work with this tool?
WEBP inputs are supported, up to 30 MB per file. For exotic formats, convert them first with one of the converter tools, then come back.
What are the size and batch limits?
You can queue 10 files per run, each up to 30 MB. Results download individually or bundled as a single ZIP.
Can I fine-tune the result before downloading?
You can adjust Width, WebP quality. Results are previewed after processing, so tweak values and re-run until the output looks right.
