Keep Aspect Ratio Preserve EXIF Metadata Grayscale Flip Horizontal Flip Vertical Transparent Background (PNG/WEBP/SVG) Remove Solid/Near-White Background

"Remove Solid/Near-White Background" is a simple color-threshold cutout best suited for product photos on a plain white or solid background — not a full AI-based background removal.

Private by design: All image processing happens entirely in your browser using the Canvas API. Your images are never uploaded to any server, ever — even in batch or developer mode.

⚙️ Developer / API Mode

This tool exposes a global window.SynetrixImageConverter object so developers can call the same conversion engine programmatically from their own page scripts — all still fully client-side, no server calls.

// Convert a File object programmatically const result = await window.SynetrixImageConverter.convert(fileObject, { format: 'webp', // jpeg | png | webp | gif | bmp | avif | svg quality: 85, // 1-100, ignored for png/bmp/gif width: 1280, // optional height: null, // optional, null = auto (aspect ratio) keepAspect: true, grayscale: false, flipH: false, flipV: false, rotation: 0, // 0 | 90 | 180 | 270 transparent: false, removeBackground: false, preserveExif: false, crop: { top:0, right:0, bottom:0, left:0 } }); // result.blob -> Blob of converted image // result.width -> output width // result.height -> output height // result.size -> output size in bytes

📖 Format Guide

JPG Best for photos. Lossy compression, small file sizes. No transparency support.

PNG Lossless quality with transparency. Ideal for logos, icons, and graphics.

WEBP Modern format. 25–35% smaller than JPG/PNG. Supports transparency. Best for web.

GIF Supports animation and transparency. Limited to 256 colors. Good for simple graphics.

AVIF Next-gen format. Excellent compression with high quality. Support depends on your browser — if unsupported, this tool falls back to JPG automatically.

SVG Wraps your raster image in an SVG container for embedding in vector-based workflows. This is not true vector tracing — line-art or logos won't become editable paths.

💡 Tips

✅Use WEBP for web images — it's smaller and faster to load.
✅Use PNG when you need a transparent background.
✅Quality 80–90% is usually indistinguishable from 100% for photos.
✅Enable "Preserve EXIF" only if you need to keep camera/GPS data — otherwise leave it off to strip metadata by default.
✅Batch convert multiple images at once, then grab them all as a single ZIP.
✅All processing is done locally — your images never leave your device.

❓ Frequently Asked Questions

Are my images uploaded to a server? ▼

No. All image conversion happens entirely in your browser using the HTML5 Canvas API. Your images are never sent to any server, stored in a database, or logged in any way — including when using batch, ZIP, or developer mode.

Which format should I use for my website? ▼

For most web images, WEBP is the best choice — it offers 25–35% smaller file sizes compared to JPG and PNG while maintaining excellent quality. If you need transparency, WEBP also supports it. For older browser compatibility, JPG (photos) or PNG (graphics/logos) are safe fallbacks.

What is EXIF metadata, and does this tool preserve it? ▼

EXIF metadata is information embedded by cameras and phones — GPS coordinates, device model, date/time, camera settings. By default this tool strips it during conversion. Toggling "Preserve EXIF Metadata" copies the original EXIF block into the converted JPEG output where technically possible (JPEG output only — other formats don't support EXIF the same way).

What quality setting should I use? ▼

For most use cases, 80–90% quality is the sweet spot — it produces files that are visually indistinguishable from 100% quality but significantly smaller. Use 100% only when you need pixel-perfect accuracy (e.g. for print). For web thumbnails or previews, 60–75% is often sufficient.

Can I convert multiple images at once and download them together? ▼

Yes. Upload as many images as you like and convert them all in one click. Afterward, use "Download All" to trigger individual downloads, or "Download ZIP" to get every converted file bundled into a single .zip archive.

Does this tool support color profile conversion? ▼

The browser's Canvas API automatically normalizes images to the sRGB color space during conversion, which covers the vast majority of web and general use cases. Preserving a custom embedded ICC profile (e.g. Adobe RGB, CMYK) is not currently supported.
