Compress Images to 100KB, 50KB, or Any Target Size

WebP Pro is a free browser application that compresses any image to an exact file size in kilobytes. Whether a portal says "file must be under 100KB" or "maximum 50KB per image", our smart binary-search algorithm automatically finds the optimal compression quality — no manual trial and error.

Traditional tools only offer a quality slider, forcing you to guess and re-export multiple times. WebP Pro's Target KB mode does the math for you: enter 100, 50, 200, or any number, and it iteratively converges on the highest-quality output that still fits under your size limit.

Convert Images to WebP for Better SEO

WebP is Google's next-generation image format. Compared to JPEG, WebP offers 25–35% better compression at equivalent visual quality. Compared to PNG, WebP can be 50% smaller. For any website, switching to WebP directly improves Largest Contentful Paint (LCP), a Core Web Vitals metric Google uses as a ranking signal.

WebP Pro converts JPG, PNG, HEIC, GIF, and BMP to WebP in one click. It also supports Lossless WebP — zero quality degradation, perfect for logos and UI components.

HEIC Support: Convert iPhone Photos Instantly

Modern iPhones shoot in HEIC format by default, which many platforms can't open. WebP Pro automatically decodes HEIC files and converts them to JPG, WebP, or PNG — entirely in your browser, no app installation needed.

100% Secure, Private, and Free

Unlike cloud-based compressors that upload your files to remote servers, WebP Pro runs entirely inside your browser using the HTML5 Canvas API. Your images are processed locally and never transmitted over any network. No account, no watermark, no file limit, no cost — ever.

Frequently Asked Questions

How do I compress an image to exactly 100KB or 50KB?

Select "Target Max Size (KB)" under Optimization Settings, type "100" or "50" in the KB box, choose your output format, upload your images, and hit Compress & Convert. The iterative algorithm automatically finds the best quality setting to get your file safely under the limit.

How do I convert JPG or PNG to WebP?

Select "Convert to WebP (Best for Web)" from the format dropdown. Upload your JPG or PNG files, set your quality or target size, and click Compress & Convert. Your converted WebP files are ready to download immediately.

Can I convert WebP back to JPG or PNG?

Yes. Select "Convert to JPG" or "Convert to PNG" from the format dropdown, upload your WebP files, and download the converted output. PNG conversion preserves any transparency in the original WebP file.

How do I convert HEIC (iPhone) photos to JPG?

Select "Convert to JPG" from the format dropdown, then drag your .heic files into the upload zone. WebP Pro automatically detects and converts HEIC to JPG entirely in your browser — no extra software or app required.

How do I compress multiple images at once (bulk)?

Hold Ctrl (Windows) or Cmd (Mac) and select multiple files in the picker, or drag and drop multiple images at once. All files are processed simultaneously. Use "Download ZIP" to get all compressed images bundled in one archive.

What is lossless WebP and when should I use it?

Lossless WebP reduces file size without any quality loss — output is pixel-identical to the original. Enable "Lossless Mode" when converting to WebP in Quality mode. Best for logos, icons, screenshots, and images where pixel-perfect quality is required.

How do I resize an image while compressing it?

Enter a target Width or Height in the Resize Dimensions fields in the settings panel. Enable "Maintain Ratio" to auto-calculate the other dimension and prevent distortion. Resize and compression happen together in one pass.

How do I compress images without changing the format?

Choose "Keep Original Format (Compress Only)" from the format dropdown. Your JPGs stay as JPGs and PNGs stay as PNGs — only the file size is reduced. Works with both Quality mode and Target KB mode.

Are my images private? Are they uploaded to a server?

Your images are never uploaded anywhere. All processing happens entirely within your browser via the HTML5 Canvas API. Nothing leaves your device — making WebP Pro the safest option for sensitive or personal photos.

Why does converting to WebP improve my website's SEO?

WebP files are 25–50% smaller than JPEG or PNG at the same visual quality. Smaller images improve page load times and Core Web Vitals scores (especially LCP), which Google uses as a direct ranking factor in search results.

Is WebP Pro completely free? Are there any limits?

Yes, 100% free. No account required, no watermarks added, no file count limits, no hidden charges. Each file can be up to 20MB. WebP Pro is and always will be completely free to use.
