Image Converter

Change an image to PNG, JPG or WebP, right here in your browser.

No image selected yet. JPG, PNG, WebP, GIF and BMP are supported.

Quality applies to JPG and WebP. PNG is always lossless.

Your image is converted on this page only. Nothing is sent to a server.

How to Use the Image Converter

  • Choose an image. Click the file button and pick a JPG, PNG, WebP, GIF or BMP image from your device.
  • Pick an output format. Choose PNG for crisp graphics and transparency, JPG for photos and smaller files, or WebP for a modern, compact format.
  • Set the quality. Move the slider to balance file size against visible quality. The slider affects JPG and WebP only, because PNG is always lossless.
  • Click Convert image. Your picture is redrawn in the new format right in your browser, with no waiting for an upload.
  • Preview and download. Check the preview, then click Download converted image to save the new file.

Key Features and Benefits

  • Five input formats. Convert JPG, PNG, WebP, GIF and BMP files without installing anything.
  • Three output formats. PNG, JPG and WebP cover almost every web, print and sharing need.
  • Quality control. A simple slider lets you shrink JPG and WebP files or keep them near-perfect.
  • Private by design. Conversion happens locally in your browser, so images are never uploaded, stored or shared.
  • Free and unlimited. No signup, no account, no watermarks and no limit on how many images you convert.
  • Works on any device. Use it on a phone, tablet or desktop in any modern browser.

Worked Examples

Example 1 — A photo for the web. You have a 4 MB PNG screenshot and your blog needs a JPG. Upload it, choose JPG at 85% quality, and download a much smaller file that still looks sharp on screen.

Example 2 — A logo with transparency. A JPG logo has a white box around it because JPG cannot store transparency. Converting a PNG version instead keeps the transparent background, so the logo sits cleanly on any coloured page.

Example 3 — A modern, smaller image. A PNG photograph is crisp but heavy. Converting it to WebP at 90% quality usually cuts the file size sharply while the picture looks the same to the eye, which helps pages load faster.

Frequently Asked Questions

Which format should I choose?

Use JPG for photographs, PNG for graphics, screenshots and anything needing transparency, and WebP when you want the smallest file that still looks great on the modern web.

Does converting change the image size in pixels?

No. The converter keeps the original pixel dimensions and only changes the file format and compression. If you also need different dimensions, use an image resizer first.

Why does the quality slider not affect PNG?

PNG uses lossless compression, which means it never throws away picture detail, so there is no quality setting to adjust. JPG and WebP are lossy formats, where a lower quality value means a smaller file.

Are my images uploaded anywhere?

No. The conversion runs entirely in your browser on your device. Your images never leave your device, are not stored on a server, and cannot be seen by anyone else.

Can I convert animated GIFs?

You can convert the first frame of a GIF to a still PNG, JPG or WebP image, but animation is not preserved. For animated output, keep the original GIF file.

Tips for the Best Results

  • Start from the best original. Converting a low-quality JPG to PNG will not restore lost detail, so always convert from the highest-quality version you have.
  • Match the format to the job. Photographs usually belong in JPG or WebP, while logos, icons and screenshots with sharp edges look best as PNG.
  • Test the quality slider. Dropping JPG quality from 95% to 85% often halves the file size with almost no visible difference, which is ideal for web pages and email attachments.
  • Check transparency before downloading. If your image has a transparent background, choose PNG or WebP, because JPG always fills transparent areas with white.
  • Keep a copy of the original. Conversion is a one-way change to the file format, so keep your original image in case you need a different format later.

Because everything happens on your device, there is no queue, no waiting for a server, and no risk that a private photo ends up in someone else’s hands. That makes this converter a safe choice for personal photos, work documents and client graphics alike, and it works just as well on a phone as it does on a desktop computer.
