A file size.
Not a guessing game.

A form asks for 500 KB. You choose 500 KB. Shrink balances quality and dimensions to fit your maximum, then shows you the result.

What’s your upload limit?Find your guide ↘

A maximum for each photo. A smaller result is OK.

Need a custom size? ↗
Less friction. More done.

Small app.
Very useful superpower.

Choose a limit, compress your photos, and get back to what you were doing.

Three steps. Then you’re done.

From too big
to ready to send.

No quality sliders to keep adjusting. Just tell Shrink how small the file needs to be.

01

Pick your photos.

Select one image or a batch of up to 20. Shrink accepts JPEG, HEIC, and PNG photos.

02

Set your limit.

Choose 200 KB, 500 KB, 1 MB, 2 MB, or enter a custom size. The maximum applies to each photo.

03

Compress. And go.

Check the before and after. Save to your Shrink album in Photos, or share straight to another app.

Already in Photos? Open the Share sheet and choose Shrink to start right there.

Your photos stay
on your iPhone.

Compression runs on your device. No photo uploads, no account to create. Work offline with locally available images.

How on-device compression works ↗

Only as small
as you need.

Choose the largest limit your upload allows. Already-small photos stay unchanged, so nothing is compressed unnecessarily.

Understand size and quality ↗
Good questions

The small
print, simply.

Everything else you might want to know before your first export.

How do I reduce photo file size on iPhone?

Choose your photos in Shrink, set a maximum size, then tap Compress. Review the result and save or share the smaller copy.
Learn More ↗

Can I compress a photo to 200 KB or 500 KB?

Yes. Both sizes are built-in presets. Each sets a maximum per photo; the final file can be smaller. Check any separate format or dimension requirements before uploading.
Learn More ↗

How do I make a photo smaller than 1 MB?

Select the 1 MB preset and compress. For a different limit, use 2 MB or Custom Size. A strict upload boundary may need a little margin below the stated limit.
Learn More ↗

Can I compress several photos at once?

Yes, up to 20 photos per batch. Your chosen maximum applies to every photo individually, so the combined batch can exceed that size.
Learn More ↗

Will compression affect image quality?

It can. Shrink adjusts quality and, when needed, dimensions to fit your limit. Use the largest permitted target and review important detail. Photos already below the target are left unchanged.
Learn More ↗

Are my photos uploaded to a server?

No. Photo compression happens on your iPhone. Locally available photos can be compressed offline. Purchases and restoring access may require a connection.
Learn More ↗

Why is my photo still rejected after compression?

The form may also require a particular format, dimensions, or a combined size limit. Confirm you selected the exported copy, then check the full upload requirements.
