Why Use This Image Compressor?
PNG compression is useful for screenshots, graphics, transparent images, and upload forms with strict file limits.
The compressor runs locally in your browser, so your images do not need to be uploaded to a remote server. It is useful for forms, profile images, web pages, product photos, and other places where file size matters.
Supported Image Formats
Upload PNG images. Downloads are optimized WebP files.
Tips to Keep Quality While Reducing File Size
PNG files can be harder to compress because they often preserve sharp edges or transparency. If the file is still too large, try reducing width or converting to WebP.

FAQs
Can I compress a PNG to 100KB?▼
Yes. Upload a PNG and the browser-based compressor will try to reduce it to 100KB or less with WebP output.
Why are PNG files harder to compress?▼
PNG files often preserve sharp edges, screenshots, logos, or transparency, so they may need resizing or WebP conversion to become much smaller.
Can I keep PNG transparency?▼
The tool outputs WebP files. WebP supports transparency in modern browsers, but always review the preview before using the download.
Should I convert PNG to WebP for a smaller file?▼
Usually yes. WebP often creates smaller files than PNG while keeping good visual quality for web use.
Can I compress PNG without uploading it?▼
Yes. The PNG is processed in your browser and is never uploaded to our servers.
