Frequently asked questions
Are my images uploaded to a server?
No. Every image is compressed, converted and edited entirely on your own device — your files never leave your browser.
Which formats can I use?
You can compress or convert between JPG, PNG, WebP and AVIF, or keep the original format.
Is there a limit on file size or number of images?
There's no hard limit. You can process many images at once; very large files are bound only by your device's available memory.
How does the target file size option work?
We automatically raise or lower the quality until the result is at or below the size you choose.
Will compressing reduce image quality?
Lossy formats (JPG, WebP, AVIF) trade a little quality for much smaller files. Use the quality slider or the before/after compare to pick the right balance. PNG stays lossless.
Is image-reducer.com free?
Yes — all tools are completely free to use.
Do you strip EXIF and GPS metadata from my photos?
Yes. Compressing an image here removes hidden metadata — including camera details and GPS location — from the file you download, as a natural side effect of how the re-encoding works. This affects only the downloaded output: the photo already stored on your device is never altered. See our Privacy page for the full picture.
Do I need to install anything or create an account?
No. image-reducer.com is a website, not an app — nothing to download or install, and no account or sign-up needed. Open the homepage and start; every tool is free, with no watermark and no usage cap.
Does image-reducer.com work without an internet connection?
Yes — once the page has loaded in your browser the first time, compressing, converting, editing, and downloading images all keep working offline. You only need a connection again to load a fresh page or check for updates.
What browsers and devices does this work on?
image-reducer.com works on the latest Chrome, Edge, Firefox, and Safari, on both desktop and mobile — anywhere a modern browser can open a webpage. The one exception: creating a new AVIF file currently only works in Chromium-based browsers, with an automatic WebP fallback everywhere else.
Can I crop, rotate, or resize an image — not just compress it?
Yes. The built-in editor lets you crop with aspect-ratio presets, rotate in 90° steps, and flip an image horizontally or vertically — and resize it to fit a maximum width and height at the same time. It all happens in the same pass as compression, with no separate tool needed.
How is this different from uploading my photo to compress it?
Many compression tools send your photo to a server, process it there, and send the result back. image-reducer.com skips that step: your image is processed inside your own browser and never sent to a server, so nothing leaves your device and there's no round trip to wait for. Other privacy-conscious tools take a similar local-processing approach — the difference here is that it's easy to verify, not that it's unique. Read how the underlying pipeline actually works.
What KB size do I need for a government exam or job-portal photo?
It depends on the exact form — exam boards and job portals each set their own KB range and pixel size, so check what your form specifically asks for. Once you know the target, target-file-size mode searches for the closest size under that budget automatically; if a photo is too detailed to fit at a usable quality, it tells you the exact number reached instead of silently failing. Our 100KB, 50KB, and 20KB guides walk through common ranges step by step, and our SSC exam guide covers photo and signature specs for that recruitment process specifically.
Do you sell or share my data with advertisers?
No. image-reducer.com carries no advertising, and none is planned, so there's no advertiser to share data with in the first place. The only information collected is anonymous, aggregate usage analytics from a self-hosted, cookieless tool we run ourselves (our host, Cloudflare, also logs standard technical access data, as with any website) — and the images you process are never sent to a server at all, so there's no image data to sell or share either. See our Privacy page for the full breakdown.
Why use WebP or AVIF instead of JPG or PNG?
WebP and AVIF are newer formats built to produce smaller files than JPG or PNG at a similar visual quality — meaning faster page loads and less storage for the same picture. WebP is the safer everyday pick, with broad support for viewing and converting; AVIF usually produces the smallest files of all, though creating one today only works in Chromium-based browsers. image-reducer.com supports all four formats — see our full format comparison, or convert a PNG to WebP directly.
