Photo Compressor — Free, Fast & Private

Phone photos are big — a single shot from a modern smartphone is 4-12MB. That is fine for storage, but too large for emailing, sharing on messaging apps, uploading to forms, or posting on websites. MiniPx shrinks photos to a fraction of their original size while keeping them sharp.

The most effective approach combines compression with dimension reduction. Most screens display photos at 1920 pixels wide or less. Reducing a 4000px phone photo to 1920px and applying Smart compression typically cuts file size by 80-90% with no visible difference on screen.

MiniPx handles all common photo formats: JPEG from any camera, HEIC from iPhones, PNG screenshots, and WebP from the web. Output as JPEG for maximum compatibility or WebP for smallest file size.

For specific use cases, MiniPx has dedicated presets. Need photos under 50KB for a government form? Under 200KB for a profile upload? Under 1MB for email? Each preset configures the optimal combination of compression and dimensions.

Everything runs in your browser. Your personal photos — family pictures, selfies, travel shots — are never uploaded to any server. Compress with confidence knowing your memories stay private.

How it works

Add your photos: Drop photos from your phone, camera, or computer. JPEG, HEIC, PNG, and WebP are all supported.
Choose compression level: Smart for everyday sharing (great quality, 60-80% smaller). Tiny for strict size limits. Gentle for minimal compression.
Set max width: 1920px for full-screen viewing. 1280px for web and email. 800px for thumbnails and form uploads.
Download smaller photos: Check the before/after file sizes, then download your compressed photos.

Frequently asked questions

How much can I compress a phone photo?

A typical 8MB phone photo compresses to 300-600KB with Smart preset at 1920px — about 92-96% smaller. At 1280px with Tiny preset, results are often under 200KB.

Will compressed photos look blurry?

With Smart preset, the difference is invisible on screens. Photos are perfectly sharp for sharing, posting, and viewing. Only extreme magnification or printing at large sizes would reveal any difference.

Can I compress HEIC photos from my iPhone?

Yes. MiniPx reads HEIC files directly in supported browsers (Safari, Chrome) and converts them to JPG or WebP during compression. No separate conversion step needed.

What is the best format for compressed photos?

JPEG is the most universally compatible — every device and app can open it. WebP produces smaller files but has slightly less compatibility with older software. For sharing via email or messaging, JPEG is the safest choice.

Can I compress multiple photos at once?

Yes. Add all your photos and compress them in batch. MiniPx shows the compressed size for each file so you can verify results before downloading.

Are my photos uploaded to a server?

No. MiniPx processes everything in your browser. Your photos never leave your device. This is the most private way to compress personal photos.
