Formats
Does converting an image remove its metadata?
Sometimes, but not dependably. Converting a JPEG to PNG or WebP can carry the EXIF straight across, drop it entirely, or keep part of it — the outcome is a property of the converter you used, not of the format you chose.
Why the answer is "it depends"
EXIF, XMP and IPTC are not features of one format. Each container has its own way of holding them: JPEG uses APP segments, PNG uses text chunks such as tEXt and zTXt, and WebP stores them in named chunks inside a RIFF wrapper. All three can carry the same descriptive information.
So a converter has a choice at every conversion, and different tools make it differently. One may faithfully translate EXIF into the target container. Another may write only the pixels and silently discard everything else. A third may keep the orientation and colour profile — which it should — while dropping the rest.
What that means in practice
Treating conversion as a privacy step is the mistake. If the goal is that nobody reads your GPS coordinates, converting the file is at best an accident that might achieve it.
Two habits avoid the problem:
- Remove the metadata deliberately, as its own step, with a tool that tells you what it removed.
- Check the output rather than trusting the conversion. How to verify metadata was actually removed covers what a real check looks like.
Conversions on this site
MetaPurify's conversion pages keep the compressed picture as faithfully as the target format allows and let you decide what metadata travels with it, instead of deciding silently on your behalf:
- WebP to JPG and AVIF to JPG, for files an older application refuses to open
- PNG to JPG, where a screenshot or export is larger than it needs to be
- JPG to WebP and PNG to WebP, for smaller files on the web
- JPG to PNG, when a lossless copy matters more than file size
Converting a lossy JPEG into PNG does not recover detail the original compression discarded — it only stops further loss from that point on. The image converter handles the same jobs when you want to pick the target format yourself.
What conversion never removes
Nothing in the visible picture changes. A landmark, a street sign, a reflection or a visible watermark survives every conversion, because those are pixels rather than metadata. Removing information a viewer can see is a different problem, and not one a format change solves.
Common questions
Does converting a JPEG to PNG remove EXIF data?
It depends entirely on the converter. PNG can hold the same descriptive information in its text chunks, so some tools translate EXIF across and others drop it. Check the output rather than assuming the format change did the work.
Which conversion reliably strips metadata?
None of them, as a rule you can depend on. If removal is the goal, remove the metadata as its own deliberate step and verify the result; treat any stripping that a conversion happens to do as a side effect.
Does converting an image lose quality?
Converting to a lossless format such as PNG stops further loss but cannot restore detail an earlier JPEG compression already discarded. Converting into a lossy format re-compresses the picture, so quality does drop.
Will converting remove a visible watermark?
No. A watermark drawn into the picture is made of pixels, so it survives every format change. Conversion only affects how the file is encoded and what metadata travels with it.
