FAQ

What image formats are supported?

We currently support JPEG, PNG, and WebP formats for import. The output will be standardized to JPEG format, which is ideal for reducing file size.

Will the image quality be reduced?

The tool works by thinning out detailed information that is hard for the human eye to perceive. If you set the slider to around "80%", you can significantly reduce the file size with almost no visible degradation.

Is it safe? Do you save my photos?

Yes, it is completely safe. All processing is done locally in your browser using JavaScript. Your photos are never uploaded to our servers, ensuring your privacy.

Why Compress Images?

Why is "lightweighting" images necessary?
From improving website speed to saving storage space on your phone, we explain the benefits.

For Webmasters & Bloggers: SEO & Page Speed

For anyone running a blog or website, Page Speed is a critical issue. Google considers loading speed (Core Web Vitals) as a ranking factor. By using Benri Lab's Image Compressor to reduce file size while maintaining quality, you can expect improved SEO performance and a better user experience (UX).

How it works: Keeping Quality High

What is Lossy Compression?

This tool uses "Lossy Compression" technology for JPEG and WebP images. This process reduces color information and groups similar colors at a level that is imperceptible to the human eye. Additionally, metadata (Exif) such as shooting date and location information is removed during processing, making it safer for privacy protection.

Everyday Use Cases

When you see a warning like "iPhone storage full," compressing your images before backing them up to the cloud or PC can save a significant amount of space. It is also useful when trying to bypass attachment size limits (e.g., 25MB) in emails or chat apps.

Compress an image in 3 steps

  1. Choose Single Mode to fine-tune one photo, or Batch Mode to compress many photos at once.
  2. Drag and drop your images, or click to select them. JPG, PNG, and WebP are supported.
  3. Move the quality slider and compare the before and after sizes, then click Save Image to download the compressed JPG.

Which quality setting should I use?

QualityBest forTypical result
85–95%Portfolio photos, printing, product shotsLittle visible change; a moderate size reduction
70–85%Websites, blogs, social media, emailUsually the best balance of quality and size
50–70%Thumbnails, chat apps, forms with strict upload limitsMuch smaller files; some softness may appear on close inspection
Below 50%Only when the file must be as small as possibleVisible blockiness and color banding

The savings depend on the original file. A 5 MB photo straight from a phone camera can often drop below 1 MB at 80% quality, while an image that was already compressed may only shrink a little.

Common reasons to compress photos

  • Email attachments: Gmail and Outlook limit attachments to about 20–25 MB per message, so compressing lets you send more photos at once.
  • Online forms and applications: job portals, rental applications, and government forms often accept images of only 1–2 MB.
  • Faster websites: smaller images improve page speed and Core Web Vitals, which helps both visitors and SEO.
  • Phone and cloud storage: compressed copies free up space when your iPhone or Google Photos storage is full.

Need a smaller file than compression alone gives?

File size depends heavily on pixel dimensions. If a photo is still too large at a reasonable quality, reduce its width and height first with the Image Resizer, then compress it. To keep a PNG or save as WebP instead of JPG, use the Image Format Converter.

More Image Compression Questions

How do I compress a photo to under 1 MB or 500 KB?

Start at around 80% quality and check the compressed size. If it is still too big, lower the quality a little at a time, or resize the image to a smaller width first. Most phone photos fit under 1 MB at 1920 px wide.

Why is the output always JPG?

JPG gives the biggest size reduction for photos and works everywhere. Transparent areas in PNG or WebP files are filled with white when they are saved as JPG.

Why is my compressed image bigger than the original?

If the original was already heavily compressed, or it is a PNG with few colors such as a logo or screenshot, converting it to JPG can make it larger. The tool flags this as Grew. Try a lower quality setting, or simply keep the original file.

Can I compress multiple images at once?

Yes. Switch to Batch Mode, add your images, and every photo is compressed with the same quality setting.

Does compressing remove location data?

Yes. Images are redrawn in your browser, so Exif metadata such as the date taken and GPS location is not included in the compressed file.

Does it work on iPhone and Android?

Yes. It runs in Safari, Chrome, and other mobile browsers with no app to install. iPhone HEIC photos should first be converted with the HEIC Converter.
