Smaller App Packages
Optimized PNG assets shrink APK/IPA size and speed up downloads.
Compress PNG for Apps
App bundles are full of PNGs — icons, splash screens, UI assets. Compress them losslessly to shrink your app package and speed up installs. All processing happens locally in your browser.

Why Choose Image Toolkit
Lossless for UI Assets
Icons and UI elements stay pixel-perfect with transparency intact.
Faster Installs
Every megabyte saved in assets is a faster install for users.
How to Use
- 1
Upload an image
Click the upload area or drag & drop a JPG/PNG image onto the page.
- 2
Choose compression quality
High quality (near-lossless), Balanced (best for web), or Maximum compression (smallest size).
- 3
Download the result
Compare the file size and savings percentage, then download with one click.
App store submission guidelines and user patience both reward smaller packages. Since PNGs dominate mobile asset bundles, lossless optimization is one of the cheapest wins in app size reduction.
How to compress app PNG assets
- Upload your PNG assets (icons, splash screens, UI elements).
- Use Balanced for lossless re-encoding.
- Download and replace the originals in your asset pipeline.
Where app PNGs pile up
- Icons — multiple densities of the same icon.
- Splash and onboarding screens — full-screen PNGs.
- UI components — buttons, illustrations and states.
A concrete example
An app ships 40 icon and UI PNGs averaging 300KB each — roughly 12MB of assets. Lossless re-encoding trims ~30% on average, saving ~3.6MB from the package: a noticeably faster install on mobile connections.
Private by design
Your app assets are processed locally in your browser — no upload, no account, no watermark.
Frequently Asked Questions
Why do app PNG assets need compression?
Design tools export PNGs with heavy metadata. App bundles ship dozens of these assets, and every unused byte inflates the package.
Is lossless compression safe for app assets?
Yes — lossless re-encoding keeps pixels identical, which is critical for icons and UI elements. Transparency is fully preserved.
Can I compress app icons?
Absolutely. App icons are small but ship in many densities; lossless optimization trims each copy without visual change.
Will this slow down my build process?
No — compress assets before adding them to the project. It's a one-time step in the asset pipeline.
Is it safe for unreleased app assets?
Yes — everything runs locally in your browser. Nothing is uploaded, so confidential app assets stay private.
