Why Compress WebP Files?
To compress a WebP image, lower its quality (70–80% usually looks the same as the original) and scale it down if it is wider than it needs to be. Teasoft's WebP Compressor does both in your browser, keeps transparency and keeps the file as WebP: add your images, set the quality and an optional maximum width, click Compress images and download the smaller files.
WebP is already one of the most efficient image formats, but a WebP file isn't automatically small. Images exported at a high quality setting, lossless WebPs, large camera-sized images converted to WebP, and files saved from a tool or plugin with default settings can all be much heavier than they need to be. On a website, that costs loading time.
There are two ways to shrink a WebP, and this tool gives you both:
1. Lower the quality. Lossy compression discards fine detail the eye barely notices. Going from a high-quality or lossless WebP to around 75% is often the biggest saving.
2. Reduce the dimensions. A 4000 px image shown at 1200 px wide wastes most of its pixels. Limiting the width removes them, and that saving is often bigger than quality alone.
Transparent backgrounds are kept, so logos, product cut-outs and graphics still work on any background.
Common reasons to compress WebP files:
- Your pages load slowly because of heavy images, and you want better Core Web Vitals.
- A website, store or CMS rejects images over a size limit.
- You exported WebPs at high quality or lossless and want lighter versions.
- You are tidying a media library before a redesign, migration or CDN move.
- You are preparing images for email, a newsletter or an app.
- You are running out of storage or hosting space.
What each setting does:
| Setting | What it does | When to use it |
|---|---|---|
| Quality | Lower values make smaller files with more compression. Default is 75%. | Almost always. 70–80% usually looks the same as the original. |
| Limit width | Scales images wider than your limit down to it. Narrower images are left alone. | Big images, or any image bigger than it will be displayed. |
Good to know
- Compression is lossy. Lower quality means smaller files but some lost detail. A WebP that was already compressed gets compressed a second time, so keep your originals until you've checked the results.
- Don't compress the same WebP over and over. Each pass removes a little more detail. Compress once from your original.
- Gains are smaller than for JPG or PNG. WebP is already efficient, so a file that was already saved at a moderate quality may not shrink much. Check the size after compressing.
- Some older software can't open WebP. Recent browsers, phones and editors can, but some print services, upload forms and old programs still ask for JPG or PNG. For those, use WebP to JPG.
What You Can Do With This Compressor
- Control the quality. The slider starts at 75%. Lower values make smaller files, and 70–80% usually looks the same as the original.
- Transparency kept. Transparent backgrounds and soft edges stay transparent, so logos and cut-outs still work on any background.
- Limit the width. Set a maximum width in pixels. Wider images are scaled down, narrower ones are left untouched.
- Stays WebP. Your files keep the format built for fast websites, with no conversion step.
- Compress in bulk. Add up to 50 WebP files at once, each up to 100 MB, and download them all as one ZIP.
- Private by design. Files are processed in your browser and never uploaded to a server, which matters for client images, product photos and unreleased designs.
- Add files your way. Drag and drop, browse, or paste with Ctrl+V.
- No sign-up, no watermark, no fees.
- Works on any device. Windows, Mac, Linux, Android and iPhone, in any modern browser.
Which Image Tool Should I Use?
Use the WebP Compressor when you have WebP files and want them smaller as WebP. If your files are JPG or PNG, converting them to WebP is usually the bigger saving. If a WebP won't open somewhere, convert it to JPG. For a mixed folder, use the general Image Compressor.
How to Compress WebP Images (3 Steps)
Add your WebP images
Drag and drop your files, click browse, or press Ctrl+V to paste. You can add up to 50 WebP files, each up to 100 MB.
Choose your settings
Open Settings. Keep quality around 70–80%. If your images are larger than they are displayed, set a maximum width such as 1600 px for photos or 1920 px for full-width banners.
Compress and download
Click Compress images, check the sizes and how the images look, then save each file or use Download to get everything in one ZIP.
Tip: if a file is still too big, lower the quality a little or set a smaller width, then compress again from your original (not from the compressed copy).
Which Settings Should I Use?
| Goal | Quality | Limit width |
|---|---|---|
| Blog and website photos | 70–80% | 1200–1600 px |
| Full-width banners and hero images | 75–80% | 1920 px |
| Product photos where detail matters | 80–85% | 1600–2000 px |
| Thumbnails and card images | 60–75% | 400–800 px |
| Logos and graphics with sharp edges | 80–90% | About 2× the size it is shown at |
| Email, newsletters and attachments | 65–75% | 1200–1600 px |
| Storage and backups | 70–80% | Leave empty |
These are starting points, not guarantees. Check the size and the look of the result, then adjust.
How to get a WebP under a size limit (for example 100 KB, 200 KB or 1 MB):
This tool does not target an exact file size, so use this routine: set a maximum width that suits the image (width gives the biggest saving), start at 70–75% quality, then check the size. If it is still too big, lower the quality in steps of 5–10% or reduce the width, and compress again from your original. Photos with lots of fine detail shrink less than simple images.
Compress WebP, convert it, or leave it?
| Choose | When |
|---|---|
| Compress WebP (this tool) | The image is for a website or app and should stay WebP, with transparency if it has any. |
| WebP to JPG | The image must open everywhere: email attachments, print services, upload forms, older software. |
| Leave it alone | It is already small (for example a tiny icon) or already saved at a moderate quality. |
Tips for compressing WebPs
- Keep the original files until you've checked the compressed versions.
- Compress from the original each time, not from an already compressed copy.
- Check images with transparency on both light and dark backgrounds.
- Use one setting for the whole batch. If some images need different treatment (for example detailed product photos), compress them separately at a higher quality.
- Have JPG or PNG files? Convert them with JPG to WebP or PNG to WebP, or use the Image Compressor to compress them in their own format.
Frequently Asked Questions
How do I compress a WebP image?
Open Teasoft's WebP Compressor, add your images, keep quality around 70–80%, optionally set a maximum width, click Compress images and download the smaller WebP files individually or as a ZIP.
How can I reduce the size of a WebP without losing quality?
You can't remove all loss, but you can get a much smaller file with little visible change. Keep quality at 70–80% and limit the width to the size you actually need. At these settings most images look nearly identical but are noticeably smaller.
What quality should I use for WebP?
The default is 75%, and 70–80% usually looks the same as the original. Use 80–90% for detailed product photos and graphics with sharp edges, and go lower (60–70%) only for small thumbnails where file size matters most.
Does compressing a WebP keep transparency?
Yes. Transparent backgrounds and soft edges are kept, so the compressed WebP still works on any background.
Does compressing a WebP reduce quality?
Slightly, because the compression is lossy. At 70–80% the difference is usually hard to see at normal viewing sizes. If the file was already compressed, this adds a second round of compression, so keep your originals in case you need full quality later.
What does the "Limit width" setting do?
It scales down any image wider than the value you enter, in pixels, and keeps the proportions. Images that are already narrower are left as they are. Reducing the width is often the biggest saving for large images.
How do I compress a WebP to 100 KB, 200 KB or 500 KB?
The tool doesn't target an exact size, but you can get there in a few tries. Set a smaller maximum width, start at 70% quality and check the file size. Lower the quality a little and compress again from your original until it fits.
Why didn't my WebP get much smaller?
WebP is already an efficient format, so a file that was saved at a moderate quality may not shrink much. Limiting the width usually helps more than lowering quality further.
Why did my compressed WebP get bigger?
It shouldn't. If the compressed version would be the same size or larger, which can happen when the original was already well optimised, the tool keeps your original file and shows "Already well optimised, original kept". To get a smaller file, try a lower quality or a smaller width.
Will compressing a WebP change its format?
No. The file stays a WebP. If you need a JPG or PNG, use Teasoft's WebP to JPG or WebP to PNG converter.
Can I compress JPG or PNG files here?
This tool is for WebP files only. For JPG use Teasoft's JPG Compressor, for PNG use the PNG Compressor, and for several formats with a choice of output format use the Image Compressor. To turn JPG or PNG files into WebP, use JPG to WebP or PNG to WebP.
How many WebP files can I compress at once?
You can add up to 50 files in one batch, each up to 100 MB.
Are my files uploaded to a server?
No. Compression happens in your browser, and your files are never uploaded.
Can I compress WebP images on my phone?
Yes. The tool works in the browser on Android, iPhone, tablets and computers. You do not need to install an app.
Is the WebP Compressor free?
Yes. It is free, with no sign-up, no watermark and no hidden fees.
