Features

Everything you need to hit the number.

A focused tool that does one job precisely, and respects your privacy while doing it.

A hard size ceiling

Set a maximum — 20 KB to 500 KB or your own number. TrueSize verifies the encoded file and never exceeds it.

100% on-device

Every pixel is processed locally. Your photos are never uploaded and the app needs no network.

JPEG, PNG & HEIC

Import the formats your phone actually produces. Transparent PNGs are flattened onto white when converting to JPEG.

Resize & reformat

Adjust dimensions and output format alongside the size limit to get the best quality for the bytes.

Save or share

Save a new copy or open the system share sheet. Your original is never overwritten.

No account. No ads.

Nothing to sign up for, no tracking, no subscriptions in this release. Open it and compress.

How it works

Three taps from oversized to perfect.

  1. 1

    Choose a photo

    Pick from your photo library or files using the system picker. You decide what the app sees, every time.

  2. 2

    Set your limit

    Tap a quick size like 100 KB or enter a custom value. Tweak format and dimensions if you like.

  3. 3

    Compress & save

    See the verified result size, then save a new copy or share it straight to the app that needs it.

Privacy by design

Your photos never leave your phone.

TrueSize uses the system photo picker, processes images locally and collects nothing. No analytics, no cloud copies, no accounts.

FAQ

Questions, answered.

Is TrueSize really free of uploads?

Yes. Compression happens entirely on your device and no images are sent over the network.

Will my original photo be changed?

Never. TrueSize writes a new file when you save, and your original and its metadata stay untouched.

What does “size ceiling” mean?

It is a maximum. The output is verified after encoding and will not exceed the limit you set. 1 KB is 1,000 bytes.

Which formats are supported?

You can import JPEG, PNG and HEIC images. JPEG gives the strongest compression for photos.

Why can’t I see all my photos?

TrueSize uses the system photo picker, so you choose what to share. Select more items in the picker or allow broader access in your device settings.
