From the tool guide Ask a follow-upWhat this tool does
Bundle several files into a single ZIP, or open a ZIP someone sent you, without installing anything and without uploading a byte. To create an archive, drop in files or a whole folder, choose Deflate compression (or Store for speed), name it and download a standard .zip that opens on Windows, macOS, Linux, iOS and Android.
How to use it, step by step
- Choose Create a ZIP, add files or a folder, and click Create ZIP.
- Or choose Open / extract, and drop a .zip file.
- Browse the contents and download the files you need.
- Check the CRC confirmation for each extracted file.
Tips from the guide
- Photos and videos are already compressed, so ZIP saves little on them.
- Use Store for huge files you only want to bundle.
- Keep folder structure by using Add a folder.
- For very large archives, use desktop software.
Common mistakes to avoid
- Expecting password protection — this tool does not encrypt.
- Compressing files that are already compressed and expecting big savings.
- Opening ZIP64 archives over 4 GB here.
Who uses it
- Anyone sharing files. Bundle documents and photos into one download.
- Students and office users. Open ZIPs without extra software.
- Developers. Inspect an archive quickly.
How to ask a question people can answer
A good thread on the ZIP Creator & Extractor saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.
- Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
- Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
- Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
- One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
- Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
