Convert images to WebP locally. Nothing leaves your browser.

Optimizing your images for the modern web takes just three steps.
Drag & drop your JPG or PNG files into the converter. Your files stay offline on your device.
Choose your preferred quality level. Smaller files mean faster websites and better SEO.
Your browser generates WebP files via the Canvas API. Download them instantly without server delay.
Convert JPEG and PNG images into lightweight WebP for faster websites — fully private, processed directly in your browser. Reduce file size significantly while keeping visual quality high.
Large image files are the number one cause for slow websites. WebP provides superior compression, saving up to 80% of data. By processing images locally, Privacy Share ensures your media never touches the cloud.
Reducing image sizes lowers bandwidth consumption and data transfer energy. Our client-side technology avoids unnecessary server energy usage, making your web development workflow greener.
Looking for a way to convert images to WebP? Squoosh, CloudConvert and TinyPNG are all solid, well-known tools — but each makes a different tradeoff between privacy, batch convenience, and format support. Here is an honest comparison for 2026.
Privacy Share and Squoosh are the only two tools here that are 100% client-side — your images never leave your device. CloudConvert and TinyPNG are reputable, EU-based companies, but both upload your file to their servers, even if only temporarily. Privacy Share is the only option that combines zero-upload processing with batch conversion and a single ZIP download.
| Feature | Privacy Share | Squoosh | CloudConvert | TinyPNG |
|---|---|---|---|---|
| Free | ✓ | ✓ | ✓ (capped) | ✓ (capped) |
| 100% client-side (no upload) | ✓ | ✓ | ✗ | ✗ |
| Batch processing (multiple files) | ✓ up to 20 | ✗ one image at a time | ✓ | ✓ up to 20/batch |
| ZIP download | ✓ | ✗ | ✓ | ✗ individual downloads |
| Free usage limit | None | None | ~10–25 conversions/day | 500 free/month via API |
| File retention | Never uploaded | Never uploaded | Temporary server storage | Up to 48h, then deleted |
| Server location | Germany (EU) | N/A (runs in your browser) | Germany-based company (cloud infra) | Netherlands (EU) |
Best for: Power users who want to manually fine-tune compression settings — quality sliders, codec choice, and a before/after comparison view — for a single image at a time. Built by Google Chrome Labs and open-source.
Watch out for: Squoosh has no built-in batch mode: you compress one image, download it, and repeat for every file. There is no ZIP export for multiple images.
Best for: One-off conversions across many different file formats — not just images — when you don't mind uploading your file.
Watch out for: Your file is uploaded to CloudConvert's servers for processing (temporarily stored, transmitted via SSL). The free plan is capped at roughly 10–25 conversions per day; regular batch use requires a paid subscription.
Best for: Developers who want excellent smart-lossy PNG/JPEG compression, especially via the Tinify API in a build pipeline.
Watch out for: The main web tool uploads your images to TinyPNG's servers, where they are stored for up to 48 hours before deletion. The free web tool also has no ZIP download — you download each result individually.
Best for: Batch-converting and resizing JPG/PNG images to WebP entirely offline in your browser, with a single ZIP download at the end — no account, no upload, no daily limit.
Tradeoff: Only converts to WebP (not AVIF, JPEG-XL, or other formats), and there is no manual per-image codec comparison view like Squoosh's.
Unlike our other tools, GDPR hosting-location isn't the main differentiator here — Squoosh, CloudConvert and TinyPNG are all reasonably privacy-conscious. The bigger question is whether your image ever leaves your device at all:
