Frequently Asked Questions

Quick answers to common questions
What image formats can I convert between?

The tool supports conversion between PNG, JPG, JPEG, WebP, GIF, BMP, and ICO formats. You can convert from any supported format to any other supported format. PNG offers lossless compression with transparency support, ideal for logos and graphics. JPG/JPEG provides lossy compression optimized for photographs, with adjustable quality (1-100). WebP combines the best of both—superior compression with transparency, supported by 95%+ browsers. GIF supports simple animations with 256 colors. BMP is uncompressed (large files). ICO is specifically for website favicons and icons. Conversion happens entirely in your browser using the Canvas API and File API for maximum privacy and speed.

Can I convert multiple images at once?

Yes! You can upload multiple images and convert them all to the same output format. Each image is processed independently, and you can download them all as a ZIP file. Batch conversion supports up to 100 images simultaneously, perfect for photographers, e-commerce sites, and content migrations. The tool generates a downloadable ZIP archive containing all converted images, preserving original filenames with new extensions (e.g., photo.png → photo.webp). Processing is parallelized for speed—multiple images convert concurrently rather than sequentially. Each image maintains its original metadata (EXIF, ICC color profiles) unless explicitly stripped. For large batches (50+ images), the tool shows progress indicators and estimated completion time.

Can I adjust image quality during conversion?

Yes! For formats that support compression (like JPG and WebP), you can adjust the quality level. Higher quality means larger file size, while lower quality means smaller file size. Quality slider ranges from 1-100: 90-100 = near-lossless (largest files, minimal artifacts), 70-85 = high quality (recommended for photos, good balance), 50-70 = medium quality (acceptable for web graphics, some artifacts visible), 1-50 = low quality (maximum compression, significant artifacts). The tool displays estimated file size before conversion—adjust quality and see real-time size predictions. For professional workflows, use 85+ quality for print/high-end displays, 70-80 for standard web use, 60-70 for mobile/low-bandwidth scenarios. WebP at quality 80 typically matches JPG at quality 85 with 25-35% smaller files.

Can I resize images during conversion?

Yes! You can specify custom dimensions or use percentage-based scaling. The tool maintains aspect ratio by default to prevent distortion. Resize options: exact dimensions (width × height in pixels), percentage scaling (50%, 75%, 200%, etc.), max dimension (scale down if larger than specified size), and fit within bounds (constrain to max width/height). Aspect ratio locking prevents stretching—changing width automatically adjusts height proportionally. Common use cases: downscaling 4K photos (3840×2160) to Full HD (1920×1080) for web, resizing product images to uniform dimensions (800×800) for e-commerce, generating thumbnails (150×150, 300×300) for galleries, and preparing images for social media (Instagram 1080×1080, Twitter 1200×675). Resampling uses high-quality Lanczos algorithm to minimize artifacts.

When should I use PNG vs JPG vs WebP?

Choose formats based on image type and use case. PNG: Use for logos, icons, UI graphics, text-heavy images, screenshots, and any image requiring transparency. Lossless compression means no quality loss, but files are larger (2-5× JPG). Supports alpha channel for transparent backgrounds. JPG: Best for photographs, realistic images, and complex gradients. Lossy compression creates smaller files but introduces artifacts at low quality. No transparency support. Use for product photos, blog post images, photography portfolios. WebP: Modern format combining PNG's transparency with superior compression (25-35% smaller than JPG, 80%+ smaller than PNG). Supported by Chrome, Firefox, Edge, Safari 14+. Ideal for web images—use JPG/PNG fallbacks for older browsers. For new projects, default to WebP with JPG fallback.

What happens to image metadata during conversion?

By default, the tool preserves EXIF metadata (camera settings, GPS location, date taken, copyright) during conversion to maintain image information. However, for privacy and file size reduction, you can strip metadata before conversion—this removes GPS coordinates, camera serial numbers, and personal data, reducing file size by 5-15 KB. ICC color profiles are preserved to maintain color accuracy across devices. For web use, consider stripping all metadata except copyright to protect privacy and minimize file size. For professional photography, preserve EXIF for copyright and editing information. Note: ICO format doesn't support EXIF—metadata is automatically removed during favicon conversion.

Can I convert animated GIFs to other formats?

Animated GIF conversion has limitations. Converting animated GIF → static formats (JPG, PNG): Only the first frame is preserved—animation is lost. GIF → WebP: Animation is preserved! WebP supports animation with better compression (typically 60-80% smaller files). Use animated WebP for modern browsers, provide GIF fallback for older browsers. The tool extracts all frames from GIF, optimizes each frame, and compiles into animated WebP with same frame timing. Frame delay and loop count are maintained. For creating animated WebP from static images, use GIF as intermediate format. Note: ICO format only supports static images—multi-frame icons require separate files or favicon stacks.

Is my image data private?

Absolutely. All image conversion happens locally in your browser. Your images are never uploaded to any server, ensuring complete privacy for your visual content. The tool uses browser-native Canvas API and File API—images are loaded into memory, processed using JavaScript, and converted entirely client-side. No network requests are made after initial page load. This is critical for: confidential business documents, personal photos (family, children), medical imagery, legal evidence, trademarked designs, and unreleased creative work. Unlike online converters that may cache or log uploads, our tool guarantees zero data retention. You can verify this by disconnecting from internet after page load—conversion continues working offline.

About This Tool

Need to convert a PNG to JPG? Or WEBP to PNG? This tool handles image conversion in your browser—no uploads to some random server. Drag and drop your image, pick the output format, convert. Supports PNG, JPG, WEBP, GIF, BMP. Pretty much every common format covered. Quality slider for lossy formats (JPG/WEBP) if you need to balance file size vs quality.

Technical Details

Uses HTML5 Canvas API for image conversion. Load the image, draw to canvas, export with toDataURL() or toBlob() in target format. For JPG/WEBP, quality parameter controls compression (0-100, higher = better quality but larger file). Maintains original dimensions. No server involved—everything happens locally.

Algorithm

Image decoding: browser decodes the source format (PNG/JPG/etc.) into a bitmap. Encoding: canvas converts the bitmap to target format. PNG uses lossless compression (perfect quality, larger files). JPG uses lossy compression (smaller files, slight quality loss). WEBP is modern and gives the best of both—good compression with quality control.
