ABOUT
ZIPMYIMAGES

A free image compressor that works entirely on your own device. Nothing is uploaded, nothing is stored.

OUR MISSION

ZipMyImages exists to solve one problem: shrinking images for the web should not require handing them to a stranger's server. Designers, developers and shop owners deal with photos every day, and most of those photos are private until the moment they are published.

So the whole tool runs inside your browser tab. Files are read from disk, re-encoded by your own processor and written back as a download. They are never sent anywhere, never logged and never stored, which also means the tool keeps working when your connection drops.

Everything is free. Guests get light guardrails on file count, file size and daily use. A free account lifts all of them: any number of files, any size, no daily cap, plus bulk resize, multi-format export and saved presets. There is no paid plan, because processing costs us nothing when it happens on your machine.

PRIVATE BY DESIGN

Every image is processed in your browser with the Canvas API and a WebAssembly JPEG encoder. Nothing is uploaded and no image data is collected.

NO WAITING ON UPLOADS

There is no round trip to a server, so a slow connection does not slow you down. Your processor does the work and results appear in seconds.

ALL THE USUAL FORMATS

JPEG, PNG, WebP, AVIF, TIFF, GIF and SVG go in; compress, convert, resize and batch rename, then take the whole set out as one ZIP.

WHO IS IT FOR?

  • Web developers trimming assets to make pages load faster
  • Designers preparing images for client hand-off or presentations
  • Online shop owners compressing hundreds of product photos
  • Bloggers and writers who need lighter images for their posts
  • Anyone who would rather not upload private photos to a cloud service

HOW IT WORKS

Compress, convert and zip your images in four steps

01

ADD YOUR IMAGES

Drag the files onto the drop zone or click to browse. JPEG, PNG, WebP, AVIF, TIFF, GIF and SVG are accepted, and the files are read straight from your disk rather than uploaded.

02

CHOOSE THE SETTINGS

Pick an output format, a quality level and a compression mode. Add bulk resizing by long side, short side, megapixels or fit box, sharpening after downscale, and a batch rename pattern if you need one.

03

PROCESS IN THE BROWSER

Press START and each image is decoded, resized and re-encoded by your own processor. Progress is shown per file, and you can cancel or retry a single image at any point.

04

DOWNLOAD THE ZIP

When the batch is done, grab everything as one ZIP archive. The summary shows how many bytes you saved and what the reduction was across the whole set.

WHICH FORMAT SHOULD I USE?

JPEG
Photographs, social posts and product shots. No transparency support.
PNG
Logos, screenshots, interface elements and anything that needs transparency.
WEBP
The safe default for websites: strong compression, quick to encode, supported everywhere.
AVIF
Smallest files, roughly 20 to 40 percent under WebP, in exchange for slower encoding.
TIFF
Input only. Camera and scanner originals are converted to a web-ready format.
GIF
Input only. The first frame is taken and optimized; animation is not preserved.
SVG
Vector files are minified when kept as SVG, or rasterized when you pick a pixel format.

WHY IMAGE OPTIMIZATION MATTERS FOR SEO

  • Largest Contentful Paint, one of Google's Core Web Vitals, is usually measured on your biggest image, so a heavy photo drags the whole score down.
  • Lighter pages open faster, and visitors who do not wait are visitors who do not leave.
  • Switching from JPEG to WebP or AVIF cuts image weight by 30 to 80 percent, which shows up immediately in PageSpeed Insights.
  • Smaller files mean less bandwidth to serve and a quicker Time to First Byte.
  • Serving images at the size they are displayed at prevents layout jumps and keeps Cumulative Layout Shift low.
