Example: a logo with a transparent background

A PNG logo with a see-through background converted to JPG gets a solid background (white unless you choose another colour), because JPG can’t store transparency. Converted to WEBP, it stays transparent and usually becomes much smaller than the PNG.

Example: a screenshot

Screenshots with text look crisp as PNG. Saved as JPG they can show faint blotches around letters, so keep screenshots as PNG unless the file must be small.

Tips

  • Uploading to a government or bank form? Convert to JPG — it is the most widely accepted format.
  • Need a specific file size? Convert first, then use the image compressor with a KB target.
  • iPhone photos (HEIC)? Use the HEIC to JPG converter.
  • Making a PDF from images? Use JPG to PDF.

What happens to transparency, animation and photo details

  • Transparency — PNG and WEBP keep see-through areas. JPG can’t, so those areas are filled with the background colour you choose.
  • Animated GIFs — only the first frame is converted, because JPG, PNG and WEBP here are still images.
  • Photo details (EXIF) — the converted file doesn’t keep camera details such as location, date and phone model. That is useful for privacy when you share photos publicly.
  • Orientation — phone photos are turned the right way up before converting, so they never come out sideways.

Who uses an image converter

  • Students and applicants whose forms accept only JPG.
  • Website owners switching images to WEBP for faster pages.
  • Designers turning PNG artwork into lighter JPGs for sharing.
  • Anyone who downloaded a WEBP image that won’t open in their app.

Frequently asked questions

How do I convert PNG to JPG?

Choose JPG under “Convert to”, then add your PNG files. They are converted right away; tap Save or Download all (ZIP). Transparent areas are filled with the background colour you choose (white by default).

How do I convert WEBP to JPG?

Add the WEBP file with JPG selected. WEBP images saved from websites often won’t open in older apps or upload forms — converting to JPG fixes that.

Which format is best?

JPG for photos (small files), PNG for screenshots, logos and text (sharp, supports transparency) and WEBP for websites (smallest, supports transparency).

Does converting lose quality?

Converting to PNG keeps every pixel. Converting to JPG or WEBP uses compression; at 90% quality the difference is very hard to see. Converting JPG to PNG won’t restore detail already lost in the JPG.

Why is WEBP missing in my browser?

Safari (iPhone and Mac) can read WEBP images but can’t create them. Use Chrome, Edge or Firefox to save as WEBP.

Are my images uploaded?

No. Conversion happens in your browser and your images stay on your device.

Does converting remove the location from my photos?

Yes. The converted image is drawn fresh from the pixels, so camera details stored in the original — including GPS location — are not copied into the new file.

Can I convert BMP, GIF or AVIF images?

Yes. Any image your browser can open — including BMP, GIF, AVIF and ICO — can be converted to JPG or PNG (and WEBP where supported). GIF animations are saved as their first frame.
