Free Image Format Converter — Convert JPG, PNG & WebP Online

Not every platform accepts every image format. Uploading a PNG to a site that only wants JPG, or sharing a WebP photo with someone whose older software cannot open it, is a frustratingly common problem. Rekreay's free Image Format Converter solves this instantly — convert any image between JPG, PNG, and WebP right inside your browser, with zero uploads, zero accounts, and zero cost. Your file never leaves your device, so your photos stay completely private.

The converter uses the HTML5 Canvas API, the same technology built into every modern browser, to decode your original image and re-encode it in whichever format you choose. JPG gives you the widest compatibility for photos. PNG preserves transparency for logos and screenshots. WebP delivers the smallest file sizes for use on websites. Whether you are a blogger optimising images for page speed, a designer preparing assets for a client, or simply someone who needs a quick format change, this tool gets the job done in seconds — no software to install, no file size limits, and no watermarks ever.

How to Convert an Image Format — Step by Step

• 1
  Upload your image. Click "Choose Image" or drag and drop a JPG, PNG, or WebP file onto the upload area. The image loads instantly inside your browser — nothing is sent to any server at any point. You will see the original file size appear in the stats bar immediately.
• 2
  Select your output format. Click the format you want to convert to — JPG, PNG, or WebP. The format flow diagram at the top of the card shows how all three formats relate to each other. You can convert in any direction: JPG to WebP, PNG to JPG, WebP to PNG, and so on.
• 3
  Adjust output quality (JPG and WebP only). Use the Quality slider to balance file size against image sharpness. A setting of 85–95% is ideal for most uses. For PNG, the quality slider is hidden because PNG is a lossless format — every PNG output is pixel-perfect regardless of settings.
• 4
  Click "Convert Image". The tool draws your image to an off-screen HTML5 canvas and re-encodes it in the format you selected. The stats bar updates to show the original size, the converted size, and whether the file grew or shrank. A preview of the converted image appears below the stats.
• 5
  Download your converted file. Click the Download button to save the result. The file is named automatically with the correct extension (for example, photo.png becomes photo-converted.jpg) so you can easily identify your converted files alongside the originals.

Frequently Asked Questions

Yes — completely free, no account, no subscription, no watermark, and no hidden file size limits. You can convert as many images as you like. Rekreay is supported by advertising, which keeps every tool free for everyone.

No. Conversion happens entirely inside your browser using the HTML5 Canvas API. Your file is never sent anywhere. This means your images stay 100% private, and the tool even works offline once the page has loaded.

It depends on your use case. WebP is ideal for websites — it delivers the smallest file sizes at any given quality level and is supported by all modern browsers. JPG is the best choice when you need maximum compatibility, especially for sharing with people using older software or devices. PNG is the right choice when your image has a transparent background, or when you need a pixel-perfect lossless copy — common for logos, screenshots, and graphic design assets.

No. Converting a JPG to PNG does not recover any quality that was lost when the original JPG was saved. JPG compression is lossy — once data is discarded it cannot be recovered by re-encoding in a lossless format. What you will get is a PNG file that is a perfect lossless copy of the JPG as it currently exists. This is useful for editing (PNG handles repeated saves without further quality loss) but it will not look sharper than the JPG you started with.

At the default quality setting of 90%, the difference between a WebP and the original JPG or PNG is invisible to the human eye under normal viewing conditions, while the file size is typically 25–50% smaller. If you set quality below 80% you may start to see compression artefacts on detailed or high-contrast images. The quality slider lets you find the exact balance that works for your image.

There is no hard limit — it is constrained only by your browser's available memory. Images up to 20–30 MB process without issue on most modern devices. Very large images (50 MB+) may be slower on older hardware, but the tool will not reject them outright.
