No uploads, no servers, and no tracing: everything runs locally on your device so your files never leave your computer. This guide shows you step-by-step how to convert images (JPG, PNG, WEBP, ICO), explains the best settings for common use cases, and provides troubleshooting tips to ensure the best output quality.
Why choose RHRnet's Image Converter?
- Privacy-first: Processing happens locally — your images never get uploaded to a remote server.

Quick overview — 4 easy steps
- Step 1 — Add your images: Drag & drop images into the upload area or click Browse Files to select files from your computer. After selection, each image shows a preview and file details.
- Step 2 — Set conversion options: Choose a target format from the Convert all to dropdown (JPG, PNG, WEBP, ICO). If needed, adjust quality for JPG/WEBP or change a single image's target format using the dropdown on its card.
- Step 3 — Convert: Click the green Convert button. A status message will indicate progress while your browser processes files locally.
- Step 4 — Download: Once conversion finishes, download images individually or use Download All (.zip) to save everything at once. Remove images with the red Clear All or the X on each card.
Detailed walkthrough
Step 1 — Add your images
You can add images either by dragging and dropping them into the upload area or by clicking Browse Files. Supported input formats include JPG, PNG, GIF, BMP, and WEBP. After adding, each image appears as a card with a thumbnail, filename, dimensions, and file size.
Step 2 — Set conversion options
The tool offers a global dropdown labelled Convert all to for quick batch conversions. If you select JPG or WEBP, a Quality slider appears — lower values give smaller files at the cost of visible compression, while higher values retain more detail.
Use the per-image dropdown to override the global choice when you need mixed outputs (e.g., convert logos to PNG for transparency and photos to JPG for smaller sizes).
Step 3 — Start the conversion
Click the green Convert button. Conversion happens in your browser and runs as a background process on your device — there is no file upload. For very large batches, your browser may show progress for each file; stay on the page until the process completes to ensure all conversions finish successfully.
Step 4 — Download your converted files
After conversion the interface updates to show new file sizes and download links. You can:
- Download individually by clicking the download button on an image card.
- Download all (.zip) to get a single ZIP containing every converted image — handy for large batches or sharing.
- Remove files with the red Clear All button or remove individual files using the X icon on each card.
Special note: ICO format
When you convert to ICO the Image Converter automatically resizes images to 256×256 pixels (a common standard for icons). If you need multiple icon sizes for legacy apps or favicon bundles, consider converting source images at different resolutions before generating an ICO file.
Best settings and use cases
Use PNG when you need lossless quality or transparent backgrounds (logos, graphics, UI elements). PNG preserves sharp edges and transparency but tends to produce larger files than JPG.
Use JPG for photographs where file size matters. A quality setting between 70–85% usually yields a good balance of size and visual fidelity for web use.
Use WEBP when you want modern compression and smaller file sizes while keeping high quality — especially useful for websites aiming for fast loading times. Keep a JPG fallback if you must support older browsers.
- Preview converted images before downloading a large batch to ensure the quality meets your needs.
- For social media, resize images to recommended dimensions first (e.g., 1200×628 for link previews) then export with the desired quality setting.
- Keep an original copy of your images if you plan to recompress or edit later; repeated JPG saves reduce quality over time.
Accessibility & SEO best practices
The Image Converter helps you prepare optimized images for the web. Use descriptive filenames and alt text (e.g., product-name-blue-front.jpg, Alt="Blue product front view") — both matter for accessibility and search engine optimization. Smaller, optimized images improve page speed, which is an important ranking factor for Google.
Troubleshooting
If a conversion fails, try these steps:
- Reload the page and add the files again.
- Check that your browser is up-to-date — modern browsers have better support for large in-browser processing.
- Reduce batch size — convert fewer files at once if you run into memory limits.
Frequently Asked Questions
- Is my image uploaded to a server?
- No. All processing is done locally in your browser — files are not uploaded.

- Common formats including JPG, PNG, WEBP, GIF, BMP. Output options include JPG, PNG, WEBP and ICO (which resizes to 256×256).
- Can I convert many images at once?
