Iminify Logo

Optimize every image on a web page at once

Paste the URL. Iminify opens the page in a real browser, collects every image it loads, runs them all through the same compressor as the upload tool, and gives you one zip to put back. No plugin, nothing installed on your site. Free with an account.

  • One URL in, one zip out
  • Same compressor, same levels
  • Reads your page, never writes to it
  • Same file names, ready to put back
Compression Level
None
No compression, only apply settings on image
Lossless
Without any visual change in the image quality
Ultra

Smart
Balance between the image quality and compression
Change Format Will allow you to convert images to different extensions

Page URL Iminify opens the page in a real browser, scrolls to the end and collects every image it loads: lazy-loaded pictures, CSS backgrounds and images on other domains included.
Create a free account to scan

Page scans come with a free account: 10 a day, up to 50 images each. Already have one? Sign in.

Maximum file size is 32 MB per image and supported formats are: PNG, JPG, JPEG, WEBP, GIF, HEIC, HEIF, TIFF, TIF
Choose the compression level that suits your images
Level What it promises What happens Pick it when
Lossless
Not one pixel changes in a JPEG, PNG or GIF The file is repacked, never re-encoded. JPEGs get an optimised Huffman table and progressive scan, PNGs a tighter deflate pass, GIFs a lossless gifsicle run. A lossy WebP has no repack step, so it is re-encoded at the highest quality the level allows. A sideways phone JPEG is rotated losslessly on the way through and keeps its colour profile. The one exception to the promise is a PNG or WebP tagged with a wide-gamut profile such as Display P3: its colours are converted to sRGB, so the values change but the picture doesn't. Logos, line art, anything you'll edit again, or when the file is evidence.
Smart
No visible change, targets 40 dB PSNR A quality search runs per image and stops at the lowest quality that still clears the target. Photos and graphics end up at different qualities because they need different ones; an image that cannot reach 40 dB inside the quality ceiling is encoded at the ceiling. Almost everything on a website. This is the default for a reason.
Ultra
Smallest file, targets 34 dB PSNR The same search with a lower target. Fine texture softens a little; edges and text stay sharp. Thumbnails, backgrounds, email images, anything shown small or blurred anyway.
None
No compression at all Only the resize, conversion or metadata setting you chose is applied. An untouched upload comes back byte for byte. You only wanted to resize or convert, and quality is someone else's decision.

Before and after

See it on real images before you upload yours

Every image a scan collects goes through this exact pipeline. These 10 samples were run at every level and every format, with nothing tuned by hand. Drag the handle, switch the level and the format, and read the numbers off the results.

Best result so far: 97.2% smaller, Ultra level, AVIF.

All 10 samples at Smart, same format: 3.89 MB in, 1.52 MB out, 61.0% smaller overall.

Fjord, from a camera

Rock, water and sky at 1800 by 1200, saved the way a camera saves it: quality 92, full chroma. Fine texture everywhere, which is where lossy encoders spend their bytes.

Drag to compare

Look the same? Good, that's the job. And no, we didn't put the same picture on both sides: the only difference you're supposed to see is the file size.

What a scan does

Exactly what happens after you press Scan

A scan is not a crawler and it is not a plugin. It opens one page in a browser the way you would, waits for it to load, scrolls to the bottom, and collects every image along the way. Here is the whole sequence.

  1. 1

    Open the page in a real browser

    Iminify loads the URL in headless Chrome, scripts and all, then scrolls to the end so lazy-loaded pictures get requested too. Nothing is written to your server.

  2. 2

    Collect every image the page shows or loads

    Every img and each size in its srcset, picture sources, video posters, CSS backgrounds, and anything a script added after the page loaded. If the browser fetched it, the scan saw it. Duplicates are removed.

  3. 3

    Download each one the way a browser would

    Each image is fetched with your page as the referrer, so hotlink protection lets it through, and identified by its bytes rather than its file extension. Images on other domains are kept too: a CDN, a storage bucket, an embed, all of it.

  4. 4

    Compress each one with your settings

    Level, format, resize and EXIF apply to every image the scan found. Each is queued on its own, so one huge file doesn't hold up the rest.

  5. 5

    Download the set as one zip

    The results table shows every image with its original size, new size and saving. Tick the ones you want and download a zip with the original file names, ready to upload back.

When to scan

Scan when the images are already live

The upload tool is for images you have on disk. The scanner is for the ones you only have on a website.

You inherited a site

A client or a previous developer built it, the media folder is a mess, and PageSpeed keeps flagging "Properly size images". Paste the slowest page and see what it weighs.

Your CMS uploads full-size originals

WordPress, Shopify and most page builders store whatever the editor dropped in, 5 MB phone photos included. A scan pulls the versions the page actually serves.

You want a before-and-after you can show someone

Total original size, total optimised size and the saving, per page, in a table. Useful for a handover, a proposal or a performance ticket.

You need the images in a new format

Turn on Change Format and every image on the page comes back as WebP or AVIF, or whichever is smaller with Auto, in one download.

Guest, account or Pro

Compress without an account, sign up for more, or go Pro and forget the caps

No trial and no card to start. A guest gets 20 images a day and a history that lives in this browser. A free account raises that to 100, opens the page scanner and keeps your history with your account for as long as you have one. Pro takes the daily caps away, doubles the size limit and puts your uploads ahead of the queue, for $6 a month.

Settings

One set of settings for the whole page

Everything you can choose for a single upload applies to every image a scan finds. The scan itself has nothing to set up.

No hunting for the images
Themes, plugins and page builders scatter pictures across folders and hosts, and you don't have to track any of that down. The page is loaded the way a visitor loads it, scripts running, and whatever it pulls in is what gets compressed.
One budget per page
A scan compresses up to 150 images from one page and gives itself about ten minutes. Both cover almost any page. A huge gallery is better scanned section by section.

Limits

What a scan will not find

  • Images on other pages. A scan reads the one URL you give it and does not follow links. Scan each page you care about.
  • Images behind a login or a cookie wall. The scan sees the page a first-time visitor sees, so anything that needs a session isn't there.
  • SVG and AVIF files, and anything above 32 MB or 64 megapixels. Those are skipped and the rest of the scan carries on.
  • Tracking pixels, and the same file under two addresses. A tracker isn't a picture, and a duplicate would only hand you a second copy.

Questions
