Sarghy WebP Converter user manual
Everything you need to convert and resize images in your browser: formats, sizes, quality, limits, and privacy. No installation — the tool runs entirely on your device.
1. What the tool does
- Converts and resizes images 100% in your browser — files never leave your device, nothing is uploaded to any server.
- Input formats: JPEG, PNG, WebP, and AVIF. Output formats: WebP, JPG, or PNG — so it also works in reverse (WebP or AVIF back to JPG/PNG).
- It is free: 30 conversions a day without an account, unlimited with a free account.
2. Step by step
- Drag and drop your images onto the upload area (or click it to browse).
- Pick the output format: WebP, JPG, or PNG.
- Optional: pick a resize width — presets 1920 / 1280 / 800 px or a custom value. The aspect ratio is kept and images are never upscaled.
- Adjust the quality slider if you want (80% is the recommended default).
- Click Convert, then download: one image downloads directly, several arrive as a single ZIP archive.
3. Limits and accounts
- Without an account: 30 free conversions per day, in batches of up to 25 images.
- With a free account (one click with Google): unlimited conversions per day and batches of up to 50 images.
- The daily counter is tracked per browser/device and resets every day.
4. Quality guide
- 80% quality is the sweet spot for most images — high visual quality with a big size reduction.
- For photos, 75–85% works best. For graphics with text, try 85–90%.
- PNG output is lossless, so the quality slider does not apply to it.
- WebP typically cuts file size by 25–35% versus JPEG/PNG at the same visual quality.
5. Privacy
- Nothing is uploaded: the entire conversion happens inside your browser.
- EXIF metadata is stripped automatically. EXIF is an invisible data card your phone attaches to every photo — date, device model, camera settings, and often the exact GPS location.
- The converted file you download is clean: the image, nothing else.
6. Troubleshooting
- "No valid image files" — the file type is not supported as input. Use JPEG, PNG, WebP, or AVIF.
- The result looks smaller than expected — check whether a resize preset is selected; choose "Original" to keep dimensions.
- AVIF files are not recognized — AVIF input needs a modern browser (current Chrome, Edge, Firefox, or Safari 16.4+).
- Hit the daily limit? It resets tomorrow — or sign in for unlimited conversions.
