Convert HEIC, WebP & PNG
+ Compress to Exact KB.
Turn iPhone .HEIC photos and .WebP files into universal JPG or PNG images—or lock your output to strict <50KB / <100KB limits for online portals.
Instant HEIC to JPG, WebP to PNG & Strict KB Image Compression
Stop uploading personal photos to slow cloud queues. OmniSave decodes Apple HEIC, Google WebP, AVIF, PNG, and JPEG files directly inside your browser's hardware-accelerated canvas.
Select JPG, PNG, or WebP as your output format, and optionally set a strict 50 KB, 100 KB, or 200 KB ceiling.
Drag and drop iPhone .HEIC photos, WebP downloads, or large camera JPEGs into the converter box.
Your converted files are generated in milliseconds inside your browser RAM and ready for immediate download.
100% Zero-Upload Privacy: Why Client-Side Conversion Matters
Traditional online image converters upload your passport scans, ID cards, and family photos to remote servers where they sit in temporary storage buckets. OmniSave's Image Converter runs entirely on your own device using WebAssembly and the HTML5 Canvas API.
When you select a strict KB target like <100 KB, OmniSave runs a multi-pass binary quantization loop in memory until your image meets the exact byte requirement without turning blurry.

Frequently Asked Questions
Are my photos uploaded to any server?
No. All HEIC decoding, format conversion, and KB compression happen 100% locally inside your web browser.
How do I compress a photo to under 100KB for an online application form?
Select 'JPG / JPEG' as the Target Output Format, set 'Exact KB Size Limit' to 'Strict < 100 KB', and drop your photo. OmniSave automatically adjusts quality and dimensions so the output stays under 100 KB.

Yes, you can drag and drop up to 20 HEIC, WebP, PNG, or JPG files simultaneously.
