Before You Upload: A Two-Minute Check
A minute of preparation prevents almost every upload problem. Two things are worth confirming before you touch the upload button: the file size, and whether you are sending one file or several.
It is also worth remembering that an upload is a snapshot. If you spot a typo after the link is out, the fix is a new upload and a new link, not an edit, so a final glance at the correct version saves a repeat trip. The quick pre-flight checklist:
- Size: the file must be 10 MB or smaller. Right-click it and choose Properties or Get Info to check.
- Naming: a meaningful name helps the recipient; invoice-final.pdf beats document1.pdf.
- Bundling: zip several files into one archive, since one link covers one file.
- Contents: confirm you have the right version, because files cannot be edited after upload.
Uploading Your File
With the file prepared, uploading is a single interaction: you select the file on the TempShare site, and the transfer begins. There is no account to create, no email address to surrender, and no password to invent. The service is anonymous by design, not anonymous as an afterthought.
When the upload finishes, you immediately receive a unique link pointing at your file. The link is generated fresh for your upload and is cryptographically random, so it cannot be guessed. One detail worth knowing: the six-hour clock starts the moment the upload completes, not when someone first clicks.
Copying and Sending Your Link
The link is short, begins with the site address, and ends with a random string of characters that identifies your file. Copy it in full, because every character matters, and paste it into whatever channel suits you: email, chat, SMS, or a ticketing system.
Send it with a line of context, including what the file is and the fact that the link expires in six hours. A recipient who knows a deadline exists is a recipient who downloads promptly, and a prompt download is the whole point of a short-lived link.
What the Recipient Sees
On the other end, the experience is one click and a download. The recipient follows your link, their browser saves the file to their device, and that is the entire ceremony. No account is required on their side either, and no software beyond a browser.
The download is forced, meaning the browser saves the file rather than opening or executing it. That matters most for unfamiliar file types, and it means the recipient never has to wonder whether clicking your link will do something unexpected.
The Six-Hour Countdown and What Comes After
Exactly six hours after the upload completes, the link stops working and the file is permanently deleted from storage. This is automatic, unconditional, and quiet: no grace period, no recovery option, and no copy kept behind the scenes.
The deletion also frees your upload slot. TempShare allows one active file per public IP address, so until the current file expires or is deleted, a second upload will not go through. After expiry, the slot is yours again and the next upload proceeds normally.
If the file expired before anyone collected it, the recovery path is refreshingly short: upload again and send the new link. A missed window costs about a minute to repair, which is a large part of why the short lifetime stays workable rather than restrictive.
Small Tips That Make Every Upload Smoother
A few habits compound nicely over time. Name files for the recipient rather than for yourself, since they are the one scanning a downloads folder an hour later. Zip before uploading whenever more than one file is involved, so the transfer is one object from end to end. If a file sits near the 10 MB limit, check whether zipping it brings it under.
It also pays to match the upload to the recipient's day. Upload when they are around and expecting the file, especially across time zones, and the six-hour window will feel generous rather than tight.
Frequently asked questions
Which file types can I upload?
Any type. TempShare does not restrict formats, only size: each file can be up to 10 MB. Files are served as forced downloads regardless of type, so nothing executes in the recipient's browser.
How do I check my file size before uploading?
Right-click the file and choose Properties on Windows or Get Info on macOS, or read the size column in your file manager. On a phone, the file details view in your files app shows the same information.
My upload will not go through. What should I check?
Two causes cover most cases: the file is larger than 10 MB, or you already have an active file and the one-per-IP limit is in play. Shrink or zip an oversized file, and wait for your current link to expire or be deleted before uploading again.
Can I send the link to several people?
Yes. The link works for anyone who has it, so you can paste it into as many conversations as you need. Everyone who clicks before the six-hour window closes gets the file, and after that nobody does.
