BriskFile

Resize for Instagram square post

Drop an image and choose which part to keep. BriskFile sizes it to 1080 × 1080 on your own device.

A instagram square post should be 1080 × 1080 pixels. Instagram re-encodes everything you upload. Sending anything wider than 1080px gains nothing and just gives their compressor more to throw away.

Nothing is uploaded. Your files are read by this page and processed by your own processor. Open the Network tab and watch — you will not see them leave.

Why that size

Instagram re-encodes everything you upload. Sending anything wider than 1080px gains nothing and just gives their compressor more to throw away.

Instagram displays feed images at 1080px wide and compresses to its own targets regardless of what you send. A 4000px original is downsampled by their pipeline, which is tuned for storage rather than for your photo.

Uploading at exactly 1080px means the only resampling is the one you controlled.

How BriskFile crops

The image is scaled until it covers 1080 × 1080, then the overflow is trimmed — so the aspect ratio is never distorted. By default the trim is centred. Open Crop & rotate and the box is locked to this shape, so you choose which part survives rather than hoping the middle was right.

BriskFile will not enlarge an image beyond its original size unless the target demands an exact size, as print and document formats do. Scaling up invents detail that was never captured, and it always looks worse than leaving it alone.

Questions

What size should a instagram square post be?

1080 × 1080 pixels. Instagram re-encodes everything you upload. Sending anything wider than 1080px gains nothing and just gives their compressor more to throw away.

Will my image be stretched?

No. BriskFile scales to fill the target and trims the overflow, keeping the aspect ratio. Open Crop & rotate to choose which part is kept instead of accepting the centre.

Is my image uploaded?

No. The resize runs in your browser using your own processor. Nothing is sent anywhere, which you can confirm in the Network tab.

What BriskFile will not do to you

  • Your files never leave your device

    Every conversion runs in your browser. Open DevTools, watch the Network tab, and you will see no upload — because there is not one.

  • No account, no email, no watermark

    Nothing to sign up for and nothing stamped on your images. There is no step between choosing a file and getting it back.

  • No limits at the download button

    No daily cap, no file counter, no "upgrade to download". If the tool starts a job, it finishes it.

  • Checkable, not just claimed

    Open the Network tab and convert something — nothing goes out. Or load the page, disconnect, and watch it keep working: the tool is already on your machine, and your file never leaves it.
