How PNG to WEBP conversion works
PNG is a common choice for graphics because it supports transparency and crisp edges. On the web, WEBP is popular because it can deliver smaller files while keeping images looking sharp — and it can keep transparency too. This converter processes your PNG files locally and exports WEBP files directly in your browser.
If you need to convert the other way for compatibility, use WEBP to PNG Converter. For photo-focused compatibility, WEBP to JPG Converter can help.
When to use this tool
Use the PNG to WEBP tool when you:
- Want smaller graphics for faster web pages while keeping transparency.
- Need lightweight assets for product pages, blogs, documentation or dashboards.
- Publish UI elements (icons, badges, overlays) and want modern web delivery.
- Prefer a modern web format over PNG for a better size-to-quality balance.
Step-by-step guide
Converting your images follows a short, repeatable routine:
- Add your PNG images. Drag files into the drop area or click to choose them from your device.
- Adjust quality. Use the slider to balance WEBP file size and detail.
- Optionally keep basic metadata. Where supported, the tool respects key information such as date and orientation.
- Convert. Start the conversion and wait for each file to be processed locally in your browser.
- Save your WEBPs. Save files one by one or use the “Save all WEBPs” button once everything is ready.
Privacy, limits and how this tool treats your images
FileYoga is built around a simple rule: your files stay with you. This PNG to WEBP converter follows that rule closely.
Local-only conversion
Images are processed in your browser. We do not upload, scan or store your files on FileYoga servers.
No hidden copies
When you clear the list or close the tab, the tool stops using your files and does not save copies on a server.
No artificial limits
No paywalls or quotas. The only limits come from your device’s memory and your browser.
No account required
Use the converter without signing up. Open the page, convert your graphics, and leave when you are done.
Limits to know about:
- Device memory: very large images or big batches can slow down your browser. Convert smaller groups if needed.
- Metadata: some browsers may not preserve all metadata when exporting images. Keep the original PNG as your master if metadata is critical.
- Compatibility: WEBP is widely supported on modern browsers, but some older apps and systems may not accept it.
Quality settings
WEBP is designed for efficient delivery. The slider lets you choose how much detail to keep versus how small you want the file to be. Higher values keep more detail but create larger files.
Helpful for large batches, quick publishing and pages where file size matters more than pixel-level detail.
A strong everyday setting. Images stay clean for most sites while keeping sizes friendly.
Best when you want extra detail for zoom, cropping or hero graphics. Files will be larger.
Photo information
Digital images can carry extra information such as date/time and orientation. This tool includes a toggle to keep basic metadata (date & orientation) when possible. Some browsers may still drop certain fields during conversion, so keep your original PNG as a master copy if needed.
Practical tips
- Use WEBP for websites and modern apps, but keep the original PNG if you may re-edit later.
- For icons and UI assets, try slightly lower quality to reduce file size while keeping clean edges.
- If a platform doesn’t accept WEBP, convert back using WEBP to PNG or WEBP to JPG Converter.
- For very large batches, close heavy tabs and convert in smaller groups to avoid memory issues.
Troubleshooting
- My WEBP is larger than the PNG. Some PNGs are already efficiently compressed. Lower the quality slider or use WEBP mainly for larger, photo-like assets.
- Transparency looks wrong. WEBP supports transparency, but preview apps can vary. Try a slightly higher quality and verify in a modern browser.
- Conversion is slow or fails. Large images and big batches can hit memory limits. Convert fewer files at once and close other tabs.
- Metadata didn’t carry over. Some browsers drop metadata during export. Keep your original PNG if metadata is important.
- An app won’t open my WEBP. Convert to PNG or JPG for compatibility using the related tools above.
Frequently asked questions
No. This converter runs locally in your browser. Your PNG images are never uploaded to FileYoga servers, and the WEBP files you download are generated on your device.
Yes. WEBP supports transparency, so transparent PNGs can remain transparent after conversion. If the output looks different in a specific app, try opening it in a modern browser or convert to PNG for maximum compatibility.
Some PNGs (especially simple graphics) can already be very compact. Lower the quality slider, or use WEBP mainly for larger assets where you want a better size-to-quality balance.
WEBP uses compression, so output quality depends on your slider setting. Higher values keep more detail. If you plan to edit the image later, keep the original PNG as your master copy.
The toggle is designed to keep basic metadata (date & orientation) when possible. Some browsers drop or limit metadata when exporting images, so not all fields are guaranteed to carry over. Keep your original PNG if metadata is critical.
There’s no artificial limit, but your device memory is the real constraint. If the browser slows down or fails, convert fewer files at once or close other heavy tabs.
Some older apps and systems don’t support WEBP. Convert your files to PNG or JPG for compatibility using FileYoga’s WEBP converters.
Yes on most modern mobile browsers, but performance depends on your device and available memory. If a batch is large, convert a smaller set at a time.
