Modern smartphones take incredible photos — but a single shot from a recent Android or iPhone can easily be 5–10MB. If you need to share these on a limited data connection or upload them to a web form, you need to compress them first.
Open Chrome or Safari on your phone, navigate to FileVit, and select a photo from your gallery. The compression runs on your phone and the result saves directly to your gallery.

You don’t need to install an app — FileVit runs entirely in your mobile browser, whether you’re on Android or iPhone.
FileVit compresses images locally on your phone's processor. Your photos are never uploaded to a remote server, which also saves mobile data since you don't transmit the original large files.
Step-by-step for Android & iPhone
- Open Chrome (Android) or Safari (iPhone).
- Navigate to the Compress Image tool.
- Tap the upload area and select photos from your gallery.
- Tap Process to compress.
- Tap Download to save the results to your gallery.
Hit a specific file size limit
If a portal requires an image to be under exactly 100KB or 200KB, use a dedicated target-size tool directly on your phone:
These tools automatically calculate the right compression level — no manual settings needed.
Reduce resolution for even more savings
If the file is still too large after compression, the issue might be the physical resolution. A 4000×3000 pixel photo will always be large, even when heavily compressed.
Use the Resize Image tool to scale it down by 50%. This dramatically reduces the file size while keeping the image looking sharp on mobile screens.
Frequently Asked Questions
Does this work on Android?
Yes. FileVit works in Chrome, Firefox, Samsung Internet, and any modern mobile browser on Android.
Will I use a lot of mobile data?
Very little. Because the processing happens on your device, only the final compressed file is handled locally — there’s no large upload to a cloud server.
Can I compress multiple photos at once?
Yes. Select multiple photos from your gallery when uploading for batch compression.
