Yes. Up to 100 MB per file and up to 3 files per request are free. Files expire in 72 hours unless you pay $2 to extend by 30 days, or pay to group them into a 30-day space for $5.

Do I need to sign up?

No. Anonymous use is the default. You can optionally attach your email so you can recover files later if you lose the share link.

How long do files last?

Free files expire in 72 hours. After that there is a 7-day grace period during which a $2 extend will bring the file back for 30 more days. After the grace period the storage is permanently purged.

Can AI agents use quik.space?

Yes. quik.space exposes an MCP (Model Context Protocol) server and accepts the x402 standard for stablecoin micropayments on Base. Agents do not need API keys or signup — their wallet is their identity.

What file types are supported?

Any file up to 5 GB. The recipient page renders inline previews for images, audio, video, PDFs, markdown, HTML (sandboxed), Microsoft Office docs, and plain text or code.

Does Slack Pro or Business+ raise the per-file cap?

No. 1 GB is the hard cap on every Slack plan as of 2026-05. Higher plans get more total storage and longer retention, but not bigger individual files.

Can I share a quik.space link in Slack?

Yes. Slack unfurls the link to show the file name and size. Recipient clicks the link to download in their browser.

Will the recipient need a Slack account to download?

No. The link opens in any browser. Recipient does not need to be in your workspace.

What about long-term storage in Slack?

Slack Free workspaces have limited file retention. quik.space files default to 72 hours but can be extended for $2 per 30 days. For longer retention than Slack itself offers, use a quik.space space for $5 per 30 days.

Does this work for files over 1 GB?

Yes. quik.space supports single files up to 5 GB. $5 one-shot for anything between 500 MB and 5 GB.

slack file size limit

Slack file size limit.

Slack caps file uploads at 1 GB per file across every plan, from Free to Enterprise. Upgrading does not raise the ceiling. The fix is to stop pushing the file through Slack and send a link instead. Drop the file on quik.space, paste the link into the Slack message, recipient clicks and downloads in their browser. The link works whether the recipient is in your workspace or not. The upload widget below produces that link in seconds.

What is happening

Slack caps file uploads at 1 GB per file across Free, Pro, Business+, and Enterprise plans as of 2026-05.

Slack normalized its file upload cap to 1 GB per file across every plan tier in 2024. Free workspaces lose access to older files after the storage retention window, which makes large uploads feel even shorter-lived than they are. The hard ceiling is 1 GB no matter how much you pay.

Common workarounds

Here is what most people try first, and where each option falls short.

Compress the file before uploading: Pack into a zip, drag into the Slack message box.; Downside. Video, photos, and PDFs barely shrink. Recipients also have to download and unzip before opening anything.
Use a Slack integration like Google Drive or Dropbox: Install the connector, share a cloud link inside Slack.; Downside. Requires every recipient to authenticate the integration. The file sits in your cloud forever unless you remember to delete it.
Upgrade to Slack Pro: Bump from Free to Pro for more storage and retention.; Downside. Does not raise the per-file cap. 1 GB is the hard limit on every plan.
Split the file before uploading: Use a split-archive tool, share each part separately.; Downside. Slow, fragile, and the recipient has to rejoin the parts. One missing piece breaks the whole archive.

The cleaner fix

Drop the file on quik.space, copy the link, paste it into the Slack message. Recipient clicks the link, downloads in their browser. Files up to 5 GB are supported, so you can clear Slack's 1 GB ceiling without compressing. Free up to 100 MB.

The upload widget at the top of this page is the same one on the homepage. Drop the file, copy the link, paste it where you wanted to attach. See pricing for the full table or how it works for the three-step explainer.

What we will not do

We do not read your file. We do not train AI on your file. We do not sell your file. Every upload is encrypted in transit over HTTPS and at rest. The share ID is an 8-character random string with roughly 218 trillion combinations, so the link is practically unguessable. After 72 hours plus a 7-day grace period, the bytes are permanently purged from storage and cannot be recovered.
