Features & Capabilities

SlimPic compresses your photos to a target file size and converts between JPG, PNG, and WebP — right on your device. Your images are never uploaded to a server.

Need a photo under 200 KB for a form, an email attachment, or a messaging app? SlimPic lets you set the target size in KB (or as a percentage of the original) and works toward it, instead of only offering a vague quality slider.

KEY FEATURES

• Compress to a target size — set a size in KB, or a ratio of the original, and SlimPic works toward it.
• Convert formats — switch between JPG, PNG, and WebP. Import HEIC/HEIF and export JPG (when your device supports decoding HEIC).
• Batch processing — pick several images and process them together; cancel anytime. One failed image won't stop the rest.
• Resize by long edge or exact resolution — limit the longest side, or fit the image into a width × height box.
• Remove EXIF — strip location and device metadata for more privacy.
• Scene presets — one tap for common cases: messaging, email, web upload, avatar, social media, ID / resume, screenshot / document.
• Smart compress — get a recommended target size based on how large your photos are; adjust anytime.
• Before / after compare — drag a slider to see the difference, with file size and savings shown.
• History — review past batches, filter by tool or status, reprocess, or save results to your gallery.
• Share in and out — open or share images into SlimPic from your gallery or other apps, then share the result anywhere.

PRIVATE BY DESIGN

SlimPic processes images locally on your phone. They are not uploaded to any server. There are no accounts and no cloud storage.

WHO IT'S FOR

• Forms and applications with a size limit (job applications, visas, ID photos)
• Sending photos via messaging apps or email that cap attachment size
• Freeing up storage space
• Converting HEIC shots from another phone to JPG

SlimPic is free. Set a target size and start compressing your photos today.

Note: HEIC/HEIF import depends on your device's decoding support. If your device can't decode a file, SlimPic will tell you instead of crashing.
