TinyByte: Photo Compress to KB

Tinybyte is a fast, offline photo compressor that reduces image size to an exact KB — without uploading anything to a server. Compress photos to 50KB, 100KB, 200KB, 500KB, or any custom size, all on your device.

WHY TINYBYTE

Most photo compressors give you vague "small / medium / large" sliders. Tinybyte lets you compress photos to an exact KB target — the size you actually need for forms, emails, and uploads. Photos stay on your phone. No account. No upload. No surprise ad video before you see your result.

WHEN YOU NEED THIS APP

- Submitting documents to online forms with strict KB limits

- Sending photos by email under attachment size caps

- Posting product photos to e-commerce marketplaces

- Reducing image size for blog or website upload

- Sharing pictures on social media without long upload times

- Freeing up storage on your phone

KEY FEATURES

📐 Compress to exact KB

Choose 50KB, 100KB, 200KB, 500KB, or set any custom target. Tinybyte finds the best quality that fits your size limit.

📷 Three quality modes

Small, Balanced (default), and High — pick the trade-off that suits the photo.

🗂️ Batch compress up to 10 photos

Process multiple photos in one queue. One bad photo never breaks the batch. Resume up to 50 in a single session with an optional reward video.

📏 Resize images

Custom width and height with aspect-ratio lock, plus presets for Email, Form Upload, Product Square, Web Image, and Social Post.

🔄 Convert format

Convert between JPG, PNG, and WebP. Adjustable quality slider for JPG and WebP.

🛡️ 100% offline processing

Your photos are read, compressed, and saved entirely on your device. Tinybyte does not operate any server that receives your photos. No account, no sign-in, no profile.

📂 Saved to a dedicated album

Compressed photos go to a "Tinybyte" album in your gallery, with descriptive filenames like compressed_186KB.jpg so you can find them later.

🕘 Local history

Re-open or re-share recent results without picking files again. Clear individual entries or all history any time in Settings.

🌗 Light and dark theme

Auto-switches with system theme.

WHAT MAKES TINYBYTE DIFFERENT

Light on ads. Most photo compressor apps interrupt you with a full-screen video ad before you can see your result. Tinybyte does not. Ads only appear after a successful save or share, with a frequency cap. No ads ever interrupt processing or block the core compression flow.

Honest about privacy. The app uses Google AdMob for ads, which collects standard advertising identifiers. We do not pretend otherwise. But your actual photos never leave the device.

PRIVACY

Photos are processed on your device. We do not operate any backend server that receives your photos or personal content. There is no account and no sign-in.

The app shows ads through Google AdMob, which collects standard advertising identifiers and diagnostic data for ad delivery. In regions where consent is required (EEA, UK), the app uses Google's User Messaging Platform to ask for consent before personalized ads are shown.

You can clear all locally stored data in Settings → Storage, or by uninstalling the app.

PERMISSIONS

Tinybyte requests the minimum permissions needed:

- Photo access only when you select a photo or save a result

- Storage Access Framework folder access only for folders you explicitly choose (in future versions)

- Internet access for ad delivery only — not for photo upload

WHAT'S COMING NEXT
