Compress Image
Drop JPG, PNG, WebP, GIF, or SVG files and shrink them locally. Pick a quality level, preview the savings, then download.
How to use Compress Image
- Drop one or more images into the upload zone, or paste from the clipboard.
- Move the quality slider. Lower values save more space; higher values keep more detail.
- Press Compress and compare original vs compressed size.
- Download a single file or a ZIP if you processed a batch.
What this tool accepts
- Runs entirely in the browser — photos are not uploaded
- Batch compress up to 20 files
- Live size comparison after processing
- Works with JPG, PNG, WebP, GIF stills, and SVG rasterization
Formats: JPG, JPEG, PNG, WebP, GIF, SVG, HEIC
Compress image is the job people type when a portal, CMS, or email client rejects a file for being too heavy — not when they want a new crop or a new format. The picture is already right; the payload is not.
This page re-encodes JPG, PNG, WebP, GIF stills, and rasterized SVG in your browser. You pick a quality level, compare original vs new kilobytes, then download. IMG 4 FIX does not receive the photo.
Use it when dimensions are already acceptable. If the shot is a 12 MP phone dump and the site only displays 1200 pixels, open Resize Image first. Quality sliders fight too many pixels.
What compress image actually changes
It changes how the pixels are stored, not how many pixels there are. JPEG and WebP throw away detail the eye is less likely to miss. PNG is rewritten as PNG so transparency stays; it is not a JPEG-style quality knob.
That is different from resize (pixel grid), crop (composition), and convert (extension). Most “reduce image size” searches need this page only after the width is already in the right ballpark.
How browser compression works here
The tool draws your picture onto an HTML canvas, then asks the browser to encode it. For JPEG, the slider maps to the standard 0–1 quality argument. WebP uses the browser’s WebP encoder. There is no MozJPEG farm and no pngquant server.
Local encoding is slightly less aggressive on some PNGs than a dedicated crush pipeline. The trade is that ID scans and unreleased product shots never sit on someone else’s disk while you wait on an upload bar.
Practical quality targets
Product photos: 80–90 so fabric and type survive. Social stories: 70–80. Thumbnails: 60–70. Screenshots with UI text: stay high or keep PNG.
Always glance at the preview on a phone-sized width. A 70% size cut that still looks sharp is a win. If a form names an exact cap (20 KB, 50 KB, 200 KB), use a compress-to-size URL instead of guessing the slider.
When not to use this compressor
Animated GIFs flatten to a still frame on canvas. Keep the original if motion matters. Camera RAW and layered PSD cannot be developed here — export JPEG from the desktop app, then compress that still.
If you need a pixel-identical archive, do not run JPEG compression. Keep the original or a PNG.
Frequently asked questions
Does compressing an image upload it to IMG 4 FIX?
No. Encoding uses the Canvas API on your device. Close the tab and the files leave memory.
Will compress image reduce quality a lot?
JPEG and WebP are lossy. Start around 75–85. If text looks muddy, raise quality. PNG recompression keeps transparency.
Can I compress several photos at once?
Yes. Select multiple files. Each image is compressed separately, then you can download a ZIP.
Should I compress or resize first?
If the photo is thousands of pixels wide, resize the long edge first. Compression then has fewer pixels to encode and usually looks cleaner.
Why did a JPEG get slightly larger?
Re-encoding a tiny, already-crushed JPEG at high quality can add bytes. Lower the slider or start from the original camera file.
Does this strip EXIF and GPS?
Yes. Drawing onto canvas writes a fresh file without the original metadata.
