About This Image Converter
An image converter is a browser-based tool that transforms image files from one format to another — JPG, PNG, WebP or GIF — without uploading files to any server. This image converter processes batches entirely client-side using the HTML5 Canvas API, with quality control and ZIP download built in.
This image converter supports four output formats: JPG for universal compatibility, PNG for lossless quality with transparency, WebP for the smallest file sizes on the web, and GIF as a fallback using PNG encoding. Upload one image or an entire batch, choose your output format, set the quality level, and convert everything in a single pass — all processing runs in your browser without any file ever reaching an external server.
Batch conversion with ZIP download is the practical standout feature here. Select a folder of images, convert all to WebP in one click, then download the complete set as a single archive. Each result row shows the original filename, output name, format badge, before/after file size and reduction percentage — so you can verify every conversion before downloading.
WebP images are 25–35% smaller than equivalent JPG files at the same visual quality, according to Google's own benchmarks. Converting your image library to WebP reduces total page weight, cuts bandwidth costs and directly improves Largest Contentful Paint (LCP) scores — the Core Web Vitals metric most influenced by image optimisation.
How to Use This Image Converter
How the Image Converter Works
- Upload one or multiple images using the upload zone above, or drag and drop them from your file manager
- Select an output format — JPG, PNG, WebP or GIF — using the four format buttons in the settings bar
- Adjust the quality slider for JPG or WebP output (range 1–100, default 85) — PNG converts losslessly and ignores the quality setting
- Click Convert All to process images sequentially, with a progress counter showing each file
- Download each converted image individually or click Download All ZIP to collect all outputs in one archive
Use Add More to append images without restarting. The Strip Metadata toggle removes EXIF data — GPS coordinates, camera details, timestamps — from every file. Canvas-based conversion strips EXIF automatically regardless of the toggle state, making it the safest choice for images shared publicly. After downloading, click Convert More Images to reset the tool for a new batch. Explore all our Image Tools for compression, resizing and colour extraction.
When to Use Each Format
- JPG — photographs and hero images where transparency is not needed; widest platform compatibility
- PNG — logos, icons, screenshots and any image requiring a transparent background
- WebP — the best default for web delivery; smaller than JPG, supports transparency, supported by all modern browsers since 2020
- GIF — simple graphics with limited colours; note that animated GIF output is not supported via Canvas
Who Uses an Image Converter
An image converter is one of the most broadly useful tools in any digital workflow. These are the audiences that reach for it most regularly:
- Web developers and SEO teams convert JPG and PNG assets to WebP to reduce page weight and hit Core Web Vitals thresholds — a 25–35% file size reduction across an image-heavy page directly improves LCP scores and search ranking
- Graphic designers convert PNG mockups to JPG for client deliverables, or convert camera JPGs to PNG before compositing — preserving transparency needed for tools like Figma, Affinity Photo or Photoshop
- Content managers and bloggers convert images to meet CMS upload restrictions; many platforms reject WebP or require JPG specifically, and a quick format conversion resolves upload failures without re-shooting
- eCommerce teams batch-convert product photography from RAW or PNG to WebP for storefronts, keeping product pages fast across all devices and connection speeds
- Social media managers convert between formats to meet platform requirements — Instagram prefers JPG, some platforms silently reject WebP, and format mismatches cause upload failures that are otherwise hard to diagnose
For size-specific requirements, see our Image Compressor or target pages such as Compress to 100KB.
Frequently Asked Questions
What is an image converter?
An image converter changes an image file from one format to another — for example from PNG to JPG, or JPG to WebP. This image converter processes files entirely in your browser using the HTML5 Canvas API, so no files are uploaded to any server at any point during conversion.
How do I convert an image format online?
Upload your images, select an output format and quality setting, then click Convert All. The tool loads each image into an HTML canvas, redraws it at original dimensions, and exports a new file using the selected format. Download individually or as a ZIP archive — all without leaving your browser.
What is the difference between JPG and PNG?
JPG uses lossy compression — it reduces file size by discarding some pixel data, making it ideal for photographs where small quality loss is acceptable. PNG uses lossless compression and supports full transparency, making it better for logos, icons and graphics with sharp edges. WebP offers the best combination: smaller than JPG and supporting transparency like PNG.
Why should I convert images to WebP?
WebP images are 25–35% smaller than equivalent JPG files at the same visual quality. Converting to WebP reduces page load times, bandwidth usage and improves Core Web Vitals scores — all of which directly affect SEO performance. All major browsers have supported WebP since 2020, making it safe for production use.
Does converting an image reduce quality?
Converting to PNG is lossless — no quality is lost. Converting to JPG or WebP applies compression controlled by the quality slider (default 85%). At 80–90% quality the difference is rarely visible on screen. Converting from JPG to PNG does not recover quality lost during original JPG compression, but produces a lossless copy at the current quality level.
Can I convert multiple images at once?
Yes. Select multiple files using the file picker or drag and drop a batch of images. All files convert to the same output format and quality setting. Download converted files individually or as a single ZIP archive using the Download All ZIP button, which appears automatically when more than one image is converted.
What image formats does this converter support?
Input formats: JPG, JPEG, PNG, WebP and GIF. Output formats: JPG, PNG, WebP and GIF. Note that browsers cannot produce animated GIF via Canvas — GIF output uses PNG encoding as a fallback. For animated GIF creation or editing, use a dedicated GIF tool.
