Image Converter

Easily convert images to JPG, PNG, WebP, or SVG online. Our tool supports batch conversion and processes files securely in your browser—no uploads required.

An image converter transforms images between different formats -- PNG, JPEG, WebP, GIF, BMP, and more. Each format uses different compression algorithms suited to different use cases: PNG for lossless graphics, JPEG for photographs, WebP for modern web optimization. This tool converts using the browser's native Canvas API, processing entirely client-side with no uploads.

Understanding Image Formats

PNG, JPEG, WebP -- when to use each

PNG (Portable Network Graphics) uses lossless DEFLATE compression, preserving every pixel exactly. It supports transparency (alpha channel) and is ideal for graphics with sharp edges: logos, icons, screenshots, and UI elements. PNG files are typically larger than JPEG for photographs because lossless compression can't exploit the smooth gradients in photos. PNG supports 8-bit (256 colors) and 24-bit (16.7 million colors) modes, plus 32-bit (24-bit + alpha).

JPEG (Joint Photographic Experts Group) uses lossy discrete cosine transform (DCT) compression, achieving 10:1 to 20:1 compression with minimal visible quality loss. It's designed for photographs and natural images with smooth gradients. JPEG doesn't support transparency and introduces compression artifacts (blocky patterns) at high compression ratios. The quality parameter (typically 70-95) controls the trade-off between file size and visual quality. JPEG is the most widely supported image format on the web.

WebP is Google's modern format that combines the best of PNG and JPEG: it supports both lossy and lossless compression, transparency, and animation. WebP files are typically 25-35% smaller than equivalent JPEGs and PNGs. It's supported by all modern browsers (Chrome, Firefox, Safari, Edge). Converting from PNG/JPEG to WebP can significantly reduce page load times. However, some older image editing software doesn't support WebP, so keeping the original is recommended.

How browser-based conversion works

Browser-based image conversion uses the Canvas API as an intermediary. The source image is loaded into an Image object, drawn onto a canvas element, then exported in the target format using canvas.toBlob() or canvas.toDataURL() with the desired MIME type and quality. This works for any format the browser can decode (PNG, JPEG, WebP, GIF, BMP, ICO) and any format it can encode (PNG, JPEG, WebP).

A limitation of canvas-based conversion is that it decodes the image into raw pixels (RGBA) and re-encodes it. This means converting from one lossy format to another (e.g., JPEG to WebP) applies compression twice, potentially degrading quality. For best results, convert from a lossless source (PNG) or use the highest quality setting. Also, EXIF metadata (camera settings, GPS location, timestamp) is typically lost during canvas conversion because the canvas only stores pixel data. Use the exif-editor tool if you need to preserve or modify EXIF data.

When to Use Each Format

JPG

Photographs and images with complex color gradients. It provides excellent compression for realistic images.

PNG

Logos, icons, and transparent images. PNG uses lossless compression to preserve sharp details.

WebP

Modern web performance. It offers high quality at significantly smaller file sizes than JPG/PNG.

SVG

Vector graphics that scale infinitely without losing quality. (Note: Converting Raster to SVG here embeds the image).

FAQ

Are my image files uploaded to your server?

No. Your privacy is paramount. All conversion processes happen directly on your computer using your browser's Canvas API and built-in image encoders. The tool reads your image files from local memory, decodes them, re-encodes them in the target format, and generates the output files — all without any network requests. Your images are never transmitted to our servers, stored in a database, or accessible to anyone but you. When you close the browser tab, all image data is cleared from memory. This makes the tool safe to use for confidential client work, medical images, legal documents, or proprietary product photos.

Can I convert SVG to PNG?

Yes. You can upload SVG files (vector graphics) and convert them to PNG, JPG, or WebP (raster formats). The tool renders the SVG at the specified resolution and exports the result as a raster image. This is useful when you need to use a vector logo or icon in a context that only supports raster images, such as social media posts, email signatures, or word processing documents. The conversion preserves the SVG's original colors, gradients, and transparency (for PNG output). You can also specify the output resolution to control the quality and file size of the result.

Does converting to SVG make my photo a vector?

No. Converting a standard photo (JPG/PNG) to SVG using this tool wraps the image in an SVG container — it does not perform vectorization (tracing). True vectorization requires specialized software like Adobe Illustrator's Image Trace or Inkscape's Trace Bitmap, which analyzes the image and creates vector paths that approximate the original. Our tool's SVG output is essentially a raster image embedded inside an SVG wrapper, which means it will not scale infinitely without quality loss like a true vector graphic. For logos and simple graphics, consider using a dedicated vector tracing tool.

What is the difference between lossy and lossless formats?

Lossy formats (JPG, WebP in lossy mode) reduce file size by discarding visual data that is less perceptible to the human eye. This results in smaller files but introduces compression artifacts, especially at high compression levels. Lossless formats (PNG, WebP in lossless mode) preserve every pixel exactly, resulting in larger files but no quality loss. As a general rule: use JPG for photographs where small file size matters more than perfect quality, use PNG for graphics with sharp edges (logos, text, screenshots) or when transparency is needed, and use WebP for modern web applications where you want the best of both worlds.

Which format should I choose for web images?

For most web images in 2026, WebP is the best choice — it provides 25-35% smaller file sizes than JPG at equivalent visual quality, and it supports transparency (unlike JPG). All modern browsers support WebP. Use JPG for photographs when you need maximum compatibility (e.g., email clients, older browsers). Use PNG for graphics with sharp edges, text, or when you need lossless quality. Use SVG for logos, icons, and simple illustrations that need to scale to any size. The tool lets you convert between all four formats, so you can experiment to find the best format for each image.

Can I convert multiple images at once?

Yes. The tool supports batch conversion — drag and drop or select multiple image files, choose the target format, and click 'Convert All'. The tool will process each image locally and package the results in a single ZIP file for download. There is no limit on the number of images you can convert in a single batch, though the practical limit depends on your device's available memory. Most modern computers can handle batches of 100-200 images without issues. A progress indicator shows how many images have been processed.

Will conversion reduce image quality?

It depends on the target format and settings. Converting from PNG to JPG will reduce quality because JPG is a lossy format — some color information and sharp details will be lost, especially in areas with fine gradients or text. Converting from JPG to PNG will not improve quality — the original JPEG artifacts are preserved, and the file size will increase. Converting between lossless formats (PNG → WebP lossless) preserves quality while potentially reducing file size. Converting from SVG to any raster format will produce a high-quality result if you specify a sufficiently high resolution (at least 2x the display size for retina screens).

Is there a file size limit?

There is no artificial file size limit imposed by the tool. Since all processing happens in your browser's memory, the practical limit depends on your device's available RAM. Most modern computers can handle images up to 50-100 megapixels without issues. Very large images (e.g., 100+ megapixel panoramas or high-resolution scanned documents) may cause the browser to become temporarily unresponsive during conversion. If you encounter issues, try converting images one at a time rather than in batch mode.
