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.

Compress an image to 100 KB

Need a photo under 100 KB for an application form or upload limit? Drop your images and ofyz lowers the quality — and the size only if needed — until each one fits under 100 KB.

  1. Drop one or more images (JPG, PNG, WebP, HEIC).
  2. The target is already set to 100 KB — change it if you need a different size.
  3. Download each image, or all of them as a ZIP.

Frequently asked questions

Will the image still look good at 100 KB?

For typical photos, yes — ofyz keeps the highest quality that fits, and only shrinks the dimensions when quality alone isn't enough.

Is the image compressor free?

Yes. It's completely free with no signup, no watermark and no file limits. Everything runs in your browser — files are never uploaded, there is no signup and no watermark.

Are my files uploaded?

No. Everything runs in your browser — files are never uploaded, there is no signup and no watermark.
