JPG vs WebP at a Glance
A quick comparison of the two formats so you can pick the right one for your image.
JPG
Best for photos and email
The most compatible image format. Small files thanks to lossy compression, but no transparency and a little quality is lost every time the file is re-saved.
WebP
Best for fast websites
A modern format with lossy and lossless modes plus transparency. Typically around 25-35% smaller than JPG at similar quality, but a few older apps cannot open it.
Good to know: A few older apps, email clients and upload forms still do not accept WebP, so keep your original JPG files as a backup. Google does not rank pages simply for using WebP, but lighter images help pages load faster, which is good for visitors. Your JPG has no transparency, so the WebP will not have any either. If you need to go back, use WebP to JPG.
JPG to WebP Converter: Frequently Asked Questions
How do I convert JPG to WebP?
Upload your JPG files with the converter above, set the quality, click Convert to WebP and download the results one by one or all together as a ZIP.
How much smaller is WebP than JPG?
WebP is typically around 25-35% smaller than JPG at similar visual quality. The exact saving depends on the image and the quality setting.
Why is my WebP file not much smaller than the JPG?
If your JPG was already heavily compressed, or you chose a very high WebP quality, the saving is smaller. Try a lower setting such as 75-80% and compare the file size and the look of the result before you download.
What WebP quality should I use?
Use 80-85% for most website photos. Go higher for images where detail matters, and lower when file size is the priority.
Does converting JPG to WebP lose quality?
Both formats are lossy, so the image is compressed again during conversion. At 80-85% quality the difference is usually not visible. Converting can only keep or slightly reduce quality, never improve it, so keep your original JPG as a backup.
Is WebP better than JPG?
For websites, usually yes: WebP files are typically smaller at similar quality, which helps pages load faster. JPG is still the safer choice for email attachments, printing and older software.
