Image Format Converter

Convert between JPEG, PNG, and WebP, with explicit transparency-to-background handling for JPEG and real output-format verification.

Format support

Converts between JPEG, PNG, and WebP only — not AVIF, GIF, SVG, HEIC, TIFF, or BMP. Every conversion checks the actual output your browser produced, not just the format you requested — if a browser can't encode to a given format, it's told about explicitly rather than silently handing back the wrong file type. Re-encoding strips EXIF, GPS, and color-profile metadata from the result.

Your image is processed locally in your browser — it is never uploaded anywhere.

Convert between JPEG, PNG, and WebP. Since JPEG can't store transparency, converting a transparent PNG or WebP to JPEG lets you pick an explicit background color to fill in — never an unpredictable default.

Every conversion verifies the actual file type your browser produced, not just the format you asked for — some browsers can silently fall back to a different format than requested, and this tool reports that explicitly instead of handing you a mislabeled file.

How to use the Image Format Converter

  1. Click the "Image (JPEG, PNG, or WebP)" file picker and choose an image; its format, pixel size, and file size appear.
  2. Pick an output in "Convert to" (your current format is not listed; WebP is preselected, or JPEG if the source is WebP).
  3. For JPEG or WebP, set the Quality slider (90% by default); for a transparent source going to JPEG, choose a Background color.
  4. Click Convert, check the preview and new file size, then click Download.

Example: Transparent PNG logo to JPEG

Load logo transparent.png, choose JPEG in Convert to, and pick a white Background color. After Convert, the transparent areas are filled with white and the result line shows the new format and file size. Download saves it as logo-transparent-converted.jpg.

Questions about the Image Format Converter

Why was my file rejected?
Only JPEG, PNG, and WebP files are accepted, up to 25 MiB and 25 megapixels. A GIF shows "Unsupported file type", and an 8000 × 6000 photo is refused as 48.0 MP over the 25 MP limit.
Is the image resized during conversion?
No. The output keeps the original pixel dimensions; use the Image Resizer if you need a different size.
Will converting to WebP or JPEG always make the file smaller?
Not always. The result shows the real output size, which depends on the image and the Quality setting. PNG output has no quality setting.
Are my photo's camera details kept?
No. Re-encoding drops EXIF, GPS, and color-profile metadata. Orientation is applied when the image is decoded, so a rotated phone photo still displays the right way up.
