What you can do
- Browse every folder of all ZIP parts together — year folders and albums.
- See the date each photo was taken (from its JSON file), the location, and which JSON file was matched.
- Filter by name, or show only files that have no date.
- Preview JPEG, PNG, GIF and WebP photos and MP4 videos (HEIC and MOV preview depends on your browser).
- When everything looks right, switch to Fix & save to get an archive with the dates applied.
Why it is fast with huge archives
A ZIP file has a table of contents at its end. The viewer reads that and the small JSON files, nothing else; a photo is only read when you open its preview. Your archive stays where it is, and nothing is uploaded.
Frequently asked questions
Can I open a Takeout ZIP without extracting it?
Yes. Drop the ZIP parts here and browse them directly. Nothing is unpacked to your disk unless you save a fixed archive.
Why can't I preview HEIC photos?
Most browsers except Safari cannot display HEIC. The file is still listed with its date and is kept in the fixed archive.
Do I have to add all the ZIP parts?
Add them all at once if you can. Google often puts a photo in one part and its JSON file in another; the tool matches them across parts by folder. Each part becomes its own fixed ZIP, so you can extract them into the same folder just like the originals.
Are my photos uploaded?
No. The ZIP files are read by your browser on your own computer and the fixed archive is written there too. Nothing is sent to a server — you can disconnect from the internet after the page has loaded and it still works.
