Quick answer
To share a large file online free, upload it to a transfer service and send the download link instead of attaching the file to an email. HeftySend supports up to 100 GB per free transfer, with three days to download and no account required for a basic send.

You do not need to divide a 12 GB project into dozens of email attachments. Gather the finished files, check the total size and give your recipient one clear place to find them. Here is the process from selecting files to checking the final delivery.

How do you send a large file with HeftySend?
- Prepare the right files. Put the final versions together. Remove unrelated working copies and give each file a meaningful name.
- Check the total size. Your complete free transfer must fit within 100 GB. Leave room for any supporting documents you still need to add.
- Open HeftySend. Use the file selector or drag your files onto the upload area.
- Let the upload finish. Keep the tab open and the device awake until the service gives you the completed transfer link.
- Check the recipient experience. Open the link in a separate browser session, inspect the file list and check the displayed expiry.
- Send the link and deadline. Tell the recipient what is included and that a free link expires after three days.
Our uploading guide explains the browser upload flow. You can also create a free account before starting if you would like to use the app with an account.
How does the recipient save the files?
The recipient opens your completed HeftySend link, checks the file list and chooses what to download. They do not need an account. Supported images, videos, audio and PDFs can be previewed before saving.
- Open the delivery page. Check that the file names match the message from the sender. Enter a password if the sender enabled one.
- Choose the download method. Use the download button beside an individual file. For a transfer of up to 10 GB in total, Download All can package multiple files into a ZIP.
- Save and check the result. Wait for the download to finish, locate the saved files and open the ones you need. A preview in the browser is not a saved copy.
- Confirm receipt before expiry. Tell the sender if a file is missing or will not open while the link is still available.
The 10 GB Download All ZIP limit is separate from the 100 GB free transfer allowance. For example, a 12 GB delivery fits the free plan, but its recipient should use individual download buttons rather than expect a generated ZIP.
For many files on a Mac or Windows computer, the free HeftySend desktop app provides another route. Paste the transfer link, choose a destination folder and download every file without creating a ZIP. Recipient downloads support resume and checksum verification without requiring an account. The app is optional; individual browser downloads remain available.
See the recipient download instructions for the product steps.
What should your delivery message say?
A useful message answers three questions: what is in the folder, which file should be used, and when does access end? You can keep it short:
Here are the final campaign files: the approved video, social images and usage notes. Please download them by the expiry shown on the page and let me know once you have everything. Use the file marked FINAL for publication.
Replace that description with your real filenames. If you send a revised version later, make the change obvious rather than leaving the recipient to guess which link is current.
Why use a link instead of an email attachment?
A download link keeps the large file out of the email itself. The message carries the address of the delivery page, while the recipient downloads the original file from there.
A dedicated HeftySend link also gives the recipient a page where they can inspect supported images, videos, audio and PDFs. That is useful when a delivery contains several kinds of file and they only need to check one before downloading.

How do you know whether a free service is enough?
- Total size: all files in one free transfer must fit within 100 GB.
- Collection time: free links expire after three days. Agree a deadline the recipient can meet.
- Download method: the browser can generate a ZIP only when the whole transfer is no more than 10 GB. Larger transfers remain downloadable using the individual file buttons.
- Local space: the recipient needs enough free storage to save the files and, for a ZIP, extract them.
For a wider choice, our free transfer service comparison separates transfer limits from shared storage and monthly credits. If you already know you need a WeTransfer replacement, use the shortlist of transfer alternatives.
What if the upload is slow or gets stuck?
First check your upload speed, which can be much lower than the download speed advertised by your internet provider. Pause other large uploads, use a reliable connection and keep the browser open. A wired connection can help when wireless reception is poor.
Check whether the original file opens locally. Note any error message and consult HeftySend’s upload troubleshooting. If only one large delivery fails, check its total size and the available limits before trying again. Do not promise the recipient a link until the upload has completed.
When should you move to a paid plan?
Upgrade when the delivery requires more than the free allowance, a longer collection period or a branded page. Custom download pages are a paid feature, not part of the free transfer allowance. Premium is listed at $9 USD per month and supports up to 1 TB per transfer with up to 365 days of availability. See the current HeftySend plans for all inclusions.
HeftySend does not charge for bandwidth usage. If you later connect your own storage, your storage provider’s separate charges still apply. For now, start with a normal free transfer and see how easily your recipient can use it.
Where do downloads go on an iPhone or iPad?
Look in the Files app after the browser finishes downloading. Apple Support’s short video shows how to find downloads on iPhone and iPad. It explains the device step after delivery, rather than demonstrating HeftySend.
Frequently asked questions
Do I have to compress the files first?
No. Upload the files directly when they fit the allowance. A ZIP is useful for packaging a folder, but it is not required for every delivery.
Will a ZIP make a large MP4 much smaller?
Often it will not, because the video is already compressed. Use a service with enough capacity if you need to preserve the original export.
Can I share the link in a messaging app?
Yes. Paste the completed transfer link into your message. Make sure you share it only with the intended recipients.
Can I close my laptop after choosing the files?
Wait until the upload finishes and you have the transfer link. Closing the tab or allowing the device to sleep can interrupt the upload.
What happens when the link expires?
The recipient can no longer rely on it to collect the files. Keep your own copy and create a new transfer if another delivery is needed.
Does free mean unlimited file size?
No. HeftySend’s free allowance is 100 GB per transfer. Unlimited bandwidth does not remove that size limit or the three day expiry.
