Just tap your target file size
$0.99
Also Included In
On sale until Oct 31. No ads or in-app purchases.
Just tap a target size to make it lighter.
This app compresses the file size of your photos to the size you set or less. Just choose 100KB, 500KB, 1MB or 2MB, or enter any target size you like, to make your iPhone pictures smaller. HEIC photos are converted and saved as JPEG (JPG), so you can upload them as they are even to websites that only accept JPEG. Compress up to 100 photos at once with a single tap.
GREAT FOR
• Submitting a photo under a limit like “1MB or less” or “500KB or less” on an application or entry form
• Bringing a résumé photo down to the required file size
• Making photos smaller before sending them as an email attachment
• Reducing the file size before uploading to a blog or website
HOW TO USE
1. Choose your photos (up to 100 at once). Tap a target size: 100KB, 500KB, 1MB or 2MB. The photo is compressed right away. (Buttons for sizes larger than the photo can't be tapped.)
2. For any other size, tap “Enter” and set it in KB or MB.
3. Check the compressed size and the quality guide, then tap “Save”.
FEATURES
• Compress up to 100 photos at once with the same setting, with the total size shown; photos already under the target are left as they are. Photos whose quality will drop are flagged at a glance.
• Works on iPad, too.
• Automatically finds the highest quality that fits within the target size.
• Shrinks the photo, keeping the aspect ratio, only when needed.
• Before saving, see the original size, the compressed size and a guide such as “Quality stays the same”.
• Your last target size is used automatically for the next photo.
• No ads and no extra purchases.
• Lightweight: the app is only about 4 MB, so it barely uses any space on your iPhone or iPad.
Note: Images with transparency aren't supported.
* Normally, the photo’s width and height stay the same and only the quality is adjusted to make it lighter. Only if that isn’t enough to reach the target is the photo scaled down slightly, keeping its aspect ratio.
