Convert Images to Any Format — Batch, Offline, No Upload

How It Works

Morpho processes your images entirely inside your browser tab. Drop one file or fifty — they are all handled locally, converted in parallel, and ready to download individually or as a single ZIP archive. There is no size limit imposed by a server, and no waiting for an upload to complete before conversion starts.

For formats that support quality settings — JPEG and WebP — you can use the quality slider to find the right balance between file size and visual fidelity. For lossless formats like PNG, TIFF, and BMP, every pixel is reproduced exactly as-is.

Supported Formats

• PNG — Lossless, supports full transparency. The go-to format for screenshots, logos, and graphics that need a clean background.
• JPEG — Lossy compression with no transparency. Produces the smallest file sizes for photographs. Quality 85–95 is near-indistinguishable from the original.
• WebP — Modern format from Google. Supports both lossy and lossless modes, and handles transparency like PNG. Smaller than JPEG at similar quality — great for the web.
• GIF — Legacy format with 256-color palette. Useful for converting old GIFs to a modern format, or converting static images to GIF for compatibility.
• TIFF — Lossless, supports high bit depth. Used in professional photography, print, and archival workflows.
• BMP — Uncompressed Windows bitmap. Very large file sizes, but fully lossless. Useful for legacy Windows software compatibility.
• QOI — Quite OK Image format. Extremely fast lossless compression — popular for game assets and real-time pipelines where decode speed matters.
• ICO — Windows icon format. Perfect for generating favicons from a PNG logo.

Use Cases

• Web optimization — Convert JPEG or PNG assets to WebP to reduce page load times and meet Core Web Vitals targets.
• Social media — Many platforms have format requirements or compress uploads aggressively. Convert to the right format first to control the output quality.
• App and game assets — Convert art assets between formats to match engine or platform requirements in bulk.
• Favicon generation — Turn a PNG logo into an ICO file for use as a browser tab icon.
• Print preparation — Convert web-format images to TIFF for print houses that require lossless input.

How to Convert Images — Step by Step

1. Open pixl.pet/converter/.
2. Drag and drop your image files onto the upload zone. Any mix of input formats is supported.
3. Select the target format using the format toggle buttons.
4. For JPEG or WebP, adjust the quality slider (default: 85). Higher means better quality and larger files.
5. Click Convert! — results appear file by file, each showing the before and after file size.
6. Download individual files or click Download All (ZIP) to get everything at once.

Your Files Stay on Your Device

All conversion happens inside your browser. No image data, no file names, and no metadata are ever sent to a server. The conversion engine is cached locally after the first visit, so the tool works even without an internet connection.

There are no file size limits imposed by upload bandwidth. Morpho processes large batches of high-resolution images as fast as your device can handle them.

What's Coming Next

• Resize and convert in one step — set target dimensions and format together, without needing a second tool.
• Smart format recommendations — Morpho will suggest the best format for your use case based on the image content.
• Preserve transparency when converting to WebP — automatic alpha channel detection and handling.

Combine Morpho with Choppy for maximum file size reduction: convert to WebP first, then compress to hit your target size. Also check out Snip for cropping images before you convert them.
