One Tool, Two Jobs

Image Studio combines the two operations creators run on every image, format conversion and dimension resize, into a single panel. Drop a file, pick the output you want, and download. No multi-step pipelines, no extra uploads, no waiting on a server.

Format conversion

Switch between JPG, PNG, and WebP. JPG for photos when file size matters, PNG for graphics with transparency or sharp text, WebP when you want both small files and good quality.

Resize

Type any width and height in pixels, or use the 25 / 50 / 75 / 100 percent presets to scale relative to the source. Lock the aspect ratio to scale proportionally, or unlock it to enter custom dimensions.

Browser-side processing

Everything runs locally in your browser using the same image decoder built into Chrome and Safari. Your image never reaches a server, which means there is no upload wait and no privacy concern.


Picking the Right Format

If you are unsure, try WebP first. It is almost always smaller than JPG without visible quality loss.

How to Use

  1. Upload an image. Drag and drop, or tap the upload area.
  2. Pick an output format. JPG, PNG, or WebP from the Convert panel.
  3. Set the size. Type custom W and H, or use a percent preset. Toggle the aspect lock to scale freely or proportionally.
  4. Download. The Result preview shows your output dimensions and estimated file size before you commit.

Frequently Asked Questions

What image formats can I convert to?
You can convert any image to JPG, PNG, or WebP. JPG works best for photos, PNG for graphics with transparency or sharp text, and WebP for the smallest file size with good quality.
Is it really free?
Yes. Image Studio is completely free with no sign-up. Everything runs in your browser, your images never leave your device.
Can I resize and convert in one step?
Yes. Set the output format and dimensions in the same panel and download a single processed file. You can lock the aspect ratio or enter custom width and height.
What is the largest image I can process?
Up to 20 MB per file. The tool is built for typical web and social media images, very large files would slow down older devices anyway.
Will my image quality drop?
PNG is always lossless. JPG and WebP use a quality slider you control, default 90 percent which is visually indistinguishable from the source for most images.
