Design Handoff to Developers
Designers can compress images for Android app directly from Figma or Sketch exports — no developer tools required. Generate a structured ZIP with all density variants ready for the Android res/drawable folders.
Understanding Android App Image Compression
What is Android Drawable Density Compression?
Android devices have screens with vastly different pixel densities — from budget phones at 160 dpi (mdpi) to flagship devices at 640 dpi (xxxhdpi). To ensure images look sharp on every screen, Android uses a density bucket system where you provide the same image at multiple resolutions. The system automatically selects the best variant for each device. Our compress image for Android app tool generates all five standard density variants from a single source image — eliminating the need to manually resize assets in Android Studio or image editors.
How Our Compress Image for Android App Tool Works
- Upload Your Source Image: Drop any image file into the drop zone. Use your highest-resolution asset as the source — ideally at xxxhdpi (4x) size or larger. The tool accepts JPEG, PNG, WebP, GIF, and BMP.
- Configure Output Settings: Set the xxxhdpi base width (the 4x size), choose your output format (PNG for icons and UI, WebP for photos), and select which density buckets to generate. All other sizes are calculated automatically using the standard Android density multipliers. Processing happens entirely in your browser — your assets never leave your device.
- Download the ZIP Archive:Click "Download ZIP" to get a structured archive with the correct
drawable-mdpi/,drawable-hdpi/,drawable-xhdpi/,drawable-xxhdpi/, anddrawable-xxxhdpi/folder structure. Drop the folders directly into your Android project'sres/directory.
Android Density Bucket Reference
- mdpi (1x, 160 dpi): Baseline density — the reference unit for all Android dp measurements. Budget and entry-level devices.
- hdpi (1.5x, 240 dpi): Medium-density screens — common on mid-range Android phones from 2012–2018.
- xhdpi (2x, 320 dpi): High-density screens — standard for most mid-range Android phones today.
- xxhdpi (3x, 480 dpi): Extra-high density — flagship Android phones and most modern mid-range devices.
- xxxhdpi (4x, 640 dpi): Ultra-high density — top-tier flagship phones. Use this as your source size for maximum quality across all densities.
Important Notes
Always start with the highest-resolution source image available — ideally at xxxhdpi size or larger. Upscaling a small image to generate larger density variants will produce blurry results. For app launcher icons, Google recommends a 1024×1024 source image. For notification icons, use a white-on-transparent PNG source. The tool preserves the aspect ratio of your source image across all density variants.

Frequently Asked Questions About Compress Image for Android App
Compressing images for Android app means resizing and optimising a source image to all five Android drawable density buckets — mdpi (1x), hdpi (1.5x), xhdpi (2x), xxhdpi (3x), and xxxhdpi (4x). Our tool generates all variants from a single upload and packages them in a correctly structured ZIP archive ready for your Android project.
The xxxhdpi base width is the pixel width of your image at 4x density — the highest standard Android density. All other sizes are derived from this: xxhdpi = 75%, xhdpi = 50%, hdpi = 37.5%, mdpi = 25%. For app launcher icons, set the base width to 192px (producing a 48px mdpi icon). For splash screens, set it to your desired full-resolution width.
Absolutely. Our compress image for Android app tool processes everything locally in your browser using the HTML5 Canvas API. Your images — including unreleased app assets and proprietary designs — are never uploaded to any server. All processing happens on your device for complete privacy.
Yes, 100% free. No signup, no subscription, no premium tier, and no file size limits. Our compress image for Android app online tool is free forever with no watermarks on generated assets.
Use PNG for icons, UI elements, and any image requiring transparency — PNG is lossless and fully supported across all Android versions. Use WebP for photographic content and background images on Android 4.0+ (API 14+) — WebP achieves 25–35% smaller files than JPEG at the same quality. Use JPEG only for photos where transparency is not needed and you need maximum compatibility with older Android versions.
Extract the ZIP and copy the drawable-* folders into your Android project's res/ directory. For example, place drawable-mdpi/icon.png into res/drawable-mdpi/icon.png. Android Studio will automatically use the correct variant for each device density. No renaming or restructuring is needed — the ZIP is already in the correct format.
For standard launcher icons, set the xxxhdpi base width to 192px — this produces 192×192 (xxxhdpi), 144×144 (xxhdpi), 96×96 (xhdpi), 72×72 (hdpi), and 48×48 (mdpi). For adaptive icons (Android 8.0+), use 108×108px at xxxhdpi to include the safe zone. Always start with a 1024×1024 source image for best quality.
Yes. Click any density bucket button to toggle it on or off. You must keep at least one density selected. This is useful when you only need to update specific density variants or when targeting a specific range of Android devices.
Yes, when using PNG output format. PNG supports full alpha channel transparency, which is preserved across all generated density variants. If you choose JPEG output, transparency is replaced with a white background. WebP also supports transparency on Android 4.0+.
