PNG Inspector & Metadata Editor
Inspect PNG structure, chunk CRCs, dimensions, bit depth and pixel statistics. Remove text, EXIF and timestamps without re-encoding image data, or add a UTF-8 text chunk.
1. Open a PNG
PNG only · up to 20 MiB, 8 million pixels. Drop one file anywhere in the workspace.
No image loaded.
PNG structure
Load an original PNG to inspect its chunks.
Removes tEXt, zTXt, iTXt, eXIf and tIME chunks. Preserves compressed image data, alpha, animation, ICC profiles and rendering chunks. Does not guarantee every possible private/custom chunk is removed.
Add a text metadata entry
Choose an image or try the example.
Your image will appear here.
Preview an operation to compare.
Pixel operations work with browser-decoded 8-bit RGBA. They can discard source metadata, color profiles or higher bit depth. PNG compression compares decoded pixels, not byte-identical files. Animated images are rejected here; use animation tools instead.
Using PNG Inspector & Metadata Editor
Inspect PNG structure, chunk CRCs, dimensions, bit depth and pixel statistics. Remove text, EXIF and timestamps without re-encoding image data, or add a UTF-8 text chunk.
- Open an original PNG or try the example. Review dimensions, bit depth, chunk CRCs and structural warnings.
- Inspect decoded pixel statistics when the image can be opened. Structure checks do not prove visual correctness.
- Download a JSON report, remove supported metadata without re-encoding, or add a text entry.
Example
Inspect a screenshot, then remove EXIF and text chunks without changing its compressed image data.
Questions & answers
Are my images uploaded for processing?
Image operations run in your browser. The website also uses ads and analytics as explained in its privacy policy.
Does this preserve every property of the original PNG?
Pixel edits use browser-decoded 8-bit RGBA and re-encode the result. Original metadata, higher bit depth and some color-profile details may be lost. The inspector’s metadata-only edits preserve image chunks.
Can I edit animated PNGs here?
These workbenches handle still images. Animated PNGs and animated WebP files are rejected to avoid silently dropping frames.
How large can my image be?
Inputs are limited to 20 MiB and 8 million pixels. Some text pixel exports have a smaller 250,000-pixel limit to keep the interface responsive.
What does exact pixel compression mean?
It verifies every decoded 8-bit RGBA pixel after re-encoding. It is not a claim that metadata, 16-bit samples or source color management are unchanged.
