Free image compressor & converter — in your browser
ofyz.image compresses, converts and resizes images entirely on your device. Nothing is uploaded, there is no sign-up and no file-size limit — drop a batch of photos and download them optimized in seconds.
How do I compress an image to a target size like 50 KB?
Turn on “Compress to a target size”, enter your target (for example 50 KB) and pick JPG or WebP. ofyz.image lowers the quality — and, if needed, the dimensions — until each image fits under the size you set.
How do I convert HEIC to JPG?
Drop your iPhone .heic photos and choose JPG as the output format. They are decoded and re-saved as JPGs right in your browser — ideal for uploading iPhone photos anywhere that will not accept HEIC.
How do I convert PNG to WebP or JPG to WebP?
Choose WebP as the output format. WebP is typically 25–35% smaller than JPG or PNG at the same quality, so it is perfect for making websites load faster.
Can I resize and batch-process many images at once?
Yes. Add dozens of images together, set a maximum width and height or a scale percentage, and download them all as a single ZIP file.
Are my images uploaded to a server?
No. Every image is processed locally on your device and never leaves your browser. EXIF metadata such as location and camera model is stripped when images are re-encoded.
