JPG to WEBP converter
Prepare lighter WEBP photos for websites with local browser processing that does not upload your JPG files.
1 KB = 1000 bytes. JPG and WebP use automatic quality and may shrink further to meet the target. PNG ignores this setting. A target is not guaranteed.
Resize settings
Keep small images sharp: Contain adds margins without enlarging pixels; Cover and Stretch may return smaller dimensions. SVG scales freely, with a maximum side of 4096 px.
Presets use Exact size and Cover. Disable “Do not enlarge” if a small image must fill the preset. The passport preset is 413 × 531 px, approximately 35 × 45 mm at 300 DPI. Set 300 DPI when printing; this preset does not write DPI metadata or check official photo requirements.
Enter whole pixel dimensions from 1 to 20000. Rendering is limited to 64 million pixels per image; available device memory may impose a lower limit.
For JPEG input with Keep size and no target: save the original bytes as .jpg. Quality and background settings do not affect these files. Original metadata, including EXIF and GPS, stays in the file.

Everything runs in your browser. Re-encoding removes EXIF metadata, including GPS, and applies the image orientation.
Rename-only output is the exception: it preserves the original file and all its metadata.
PNG preserves the decoded pixels but cannot recover detail already lost in the source. Animated images become a still image of the first frame. Very large batches depend on device memory.
Convert a website photo to WEBP
- Use JPG to WEBP by choosing a JPEG photograph intended for a product page, article or image gallery.
- Select a starting quality on the slider, remembering that your JPEG may already contain compression artefacts.
- Enter a target size only if you need a byte limit; this switches to automatic quality selection.
- Review the new file size and dimensions, then examine faces, foliage or textured areas in the saved photo.
- Download the chosen WEBP version and retain the original JPG for future edits or a different export.
Where smaller photo files help
- Lower the image payload of an article containing several photographs.
- Prepare product photography for a store that accepts WEBP uploads.
- Make portfolio photos less costly to transfer over mobile connections.
- Find a workable balance between visible detail and file weight.
- Create an alternative to a JPEG that exceeds a publishing system's size limit.
Choosing WEBP settings for photographs
Will WEBP always be smaller than JPG?
Often it is, but the result depends on the scene and the existing JPEG compression. A heavily compressed source can offer little room for further savings.
Which quality should I choose?
Start with the default and compare the downloaded photo at its intended display size. Lower quality gradually if the savings matter more than subtle texture.
Can conversion repair JPEG artefacts?
Existing blocks, blur and ringing are part of the decoded source. Changing to WEBP does not restore missing information, and additional lossy encoding can make those defects more noticeable.
What does a 150 KB target mean?
It means 150000 bytes. Automatic processing first adjusts quality and can then shrink dimensions; for example, a wide source may become narrower to approach the limit.
Which browser can produce the output?
Chrome, Edge and Firefox can encode WEBP for this converter. Safari cannot write this output format here, so the tool displays a message instead of silently substituting another format.
Why might processing fail or miss my limit?
Very small targets may remain unattainable within the available quality and resizing steps. Large photos also require device memory; check any warning and the final size before publishing.
