An iLoveIMG alternative built around compression

iLoveIMG is a toolbox: crop, watermark, meme generator, background removal. Iminify does one job. It compresses, converts and resizes in a single pass, and defines each compression level by a measurement you can check. Try it below. No account needed.

  • AVIF and WebP output
  • HEIC and TIFF accepted
  • Levels defined by measurement
Compression Level
None
No compression, only apply settings on image
Lossless
Without any visual change in the image quality
Ultra
Max compression with some quality loss
Smart
Balance between the image quality and compression
Change Format Will allow you to convert images to different extensions
Resize Will allow you to change the width, height or scale of images
Keep EXIF Will allow you to preserve meta data in images
Maximum file size is 16 MB per image and supported formats are: PNG, JPG, JPEG, WEBP, GIF, HEIC, HEIF, TIFF, TIF
Guests get 20 images a day, 20 left today. A free account gets 50 a day.
Delete this image?
The image and its optimized copy will be removed from storage. This cannot be undone.

Rename this image
Choose the name the optimized image downloads with. Its format stays the same.

Uploaded as

Rename the selected images
Each image gets this name and a number, counted in the order they were uploaded. Their formats stay the same.

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 and a perceptual score of 70 A quality search runs per image and stops at the lowest quality that still clears the PSNR target. That answer is then scored on the SSIMULACRA 2 scale, because an average over every pixel lets a mostly flat picture through at a quality its detail doesn't deserve, and when it falls under 70 the search moves back up until it doesn't. Photos and graphics end up at different qualities because they need different ones; an image that cannot reach the targets 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 and a perceptual score of 50 The same two-stage search with lower targets. 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.

Side by side

Iminify and iLoveIMG, by the numbers they publish

The iLoveIMG column is taken from iloveimg.com. Where its pages don't state something, the cell says so; we haven't guessed.

What Iminify iLoveIMG
Free compression limit 16 MB a file as a guest, 32 MB with a free account; 20 or 50 images a day 30 files a task, 200 MB a task
Formats it compresses JPG, PNG, WebP and GIF, plus HEIC and TIFF as input JPG, PNG, SVG or GIF
Compression levels Lossless, Smart and Ultra, each defined by a PSNR and a perceptual target Not stated
Output to WebP or AVIF Yes, or Auto, which keeps the smallest Not stated on the compression page
Other image tools Resize, in the same pass. Nothing else. Resize, crop, rotate, watermark, editor, meme generator, upscale, blur face, remove background, HTML to image
How long your files are kept Until you delete them. Every result has a delete button that removes the upload and the optimized copy for good. A guest can reach their results only while the browser session lasts, about two hours after the last request; after that the files stay in storage until we remove them, and an email to [email protected] gets one deleted. Kept so you can download the result, then deleted; the FAQ gives no length of time
Paid plan Pro: $36 a year or $5 a month, 90 MB files, no daily caps Premium: US $4 a month billed annually, or US $7 a month; 120 files and 4 GB a task

Different tools

A toolbox and a specialist

If you need to crop a photo, add a watermark and remove a background, iLoveIMG has a tool for each and Iminify has none. That's not what this site is for.

If the job is making images smaller for the web, the differences run the other way. Iminify writes AVIF and WebP, the two formats that save the most. It reads HEIC from iPhones and TIFF from scanners. And it shows its working: Smart searches each image for the lowest quality that still reaches 40 dB PSNR against your upload, then checks the result on a perceptual scale. An image that can't reach the target is encoded at the level's quality ceiling. You can open any result and see the PSNR for yourself.

iLoveIMG's free batch limit is the more generous one: 30 files and 200 MB a task. If you're compressing a folder of large files in one go and don't need modern formats, that may suit you better.

Files work differently too. iLoveIMG deletes them after you've downloaded your result. Iminify keeps them until you press delete, so with an account you can come back to a result or compress the same original again at another level. A guest can reach their results only while the browser session lasts, about two hours after the last request.

What survives

What you get here

  • Modern formats out

    WebP and AVIF, or Auto, which encodes each candidate and keeps the smallest for images up to about eight megapixels.

  • One encode for three jobs

    Compress, convert and resize happen in a single pass, so your image loses quality once, not three times.

  • A whole web page at once

    With a free account, the page scanner compresses every image a page loads and returns one zip.

  • No editing tools, no SVG

    No crop, watermark, background removal or SVG compression. iLoveIMG covers all of those.
