Convert Image

Converting changes the file format without changing the picture's pixel dimensions. Use it to turn a PNG into a JPG for an upload, save a screenshot as a lossless PNG, or move a heavy JPG to WebP.

  • Convert between JPG, PNG and WebP; only formats this browser can encode are listed.
  • Choose a background colour when transparency cannot be stored.
  • Read the measured conversion result before downloading.

Convert between JPG, PNG and WebP

The panel lists the three formats the tool reads and writes: JPG, PNG and WebP. It checks which ones your browser can encode and marks any it cannot as unavailable, so a download cannot carry a PNG behind a .webp name. HEIC and other phone formats are not accepted here. Export them to JPG with your phone or camera software first.

Choose the format for the job

JPG suits photographs. It is lossy and cannot store transparency, so transparent areas are flattened onto the background colour you pick, and the panel warns you before you apply. PNG is lossless and keeps transparency, which suits logos, screenshots and text, though it is often larger than the JPG it came from. WebP keeps transparency and usually produces a smaller file than JPG.

SAME 1200 × 800 PICTURE JPG Lossy No transparency PNG Lossless Keeps transparency WebP Often smaller Keeps transparency
Example: the same 1200 × 800 picture in three formats. The dimensions stay the same; file size and transparency support change.

What the result will tell you

Converting never resizes the image. The preview states the format change and confirms the dimensions stay the same. No size is promised in advance, because only a real encode can measure it. After you press Convert Image, the panel reports the before and after size, the difference and whether transparency was kept or flattened. If the new file is larger, it says so.

Pick the format the destination accepts, then check the measured result. If the file is still heavy, compress the converted copy rather than converting it again.

Common questions

Does converting an image change its dimensions?
No. Conversion changes the format and can change the file size, but the width and height stay as they are. Use Resize if the pixel count must change.
Can I convert HEIC to JPG here?
Not directly. The tool accepts JPG, PNG and WebP. Export the HEIC photo as JPG from your phone or camera app first, then load that JPG here.
