Krunch: ImageResize & Compress

Krunch is the fastest photo resizer and image compressor for Android. Resize any picture to an exact KB size, a preset, custom width × height, or a percentage — right on your phone, offline, with no ads and no watermark.

▸ ONE-TAP RESIZE MODES
• Presets — 1080p, 720p, 480p, Instagram Square (1080×1080), Story (1080×1920), Thumbnail (400×400).
• Custom dimensions — set exact width and height with a smart aspect-ratio lock.
• Percentage — scale from 5% to 150% with a live slider.
• Target KB — the killer feature. Tell Krunch "under 500 KB" and it iteratively compresses and, if needed, downscales the photo until it fits. Perfect for WhatsApp uploads, email attachments, government forms, job applications, exam registration and passport photos.

▸ FORMAT CONVERSION
Convert between JPG, PNG and WEBP with a quality slider (10–100). PNG stays lossless; JPG and WEBP get smooth compression control.

▸ BATCH RESIZE
Pick up to 20 photos and apply the same rule to every one. Watch each thumbnail update with its own progress badge and final size.

▸ SAVE & SHARE
Save straight to your Photo Gallery or open the native share sheet — send resized photos to WhatsApp, Gmail, Telegram, Instagram or any other app in one tap.

▸ HISTORY
Every resize is logged with before-and-after thumbnails and a file-size delta ("3.2 MB → 480 KB · −85%"). Rerun, reshare or delete any recent job in two taps.
