Image Compressor
Reduce image file size in bulk, with control over quality, format and width.
Drop in JPG, PNG, WebP, GIF, BMP or AVIF images and make them much smaller in one go. Choose the quality, save in WebP, JPG or PNG (or keep the original format), and optionally limit the width so oversized photos shrink even more. Add up to 50 files, download them one by one or as a ZIP. Everything runs in your browser, so nothing is uploaded. Free, with no sign-up and no watermark.

Drop images here or browse
JPG, PNG, WEBP, GIF, BMP and AVIF images, up to 50 files, 100 MB each. You can also paste with Ctrl+V.
WEBP gives the smallest files for websites. Choose JPG for photos, PNG when you need exact transparency.
Lower quality makes smaller files. PNGs are reduced to fewer colours, like TinyPNG. 60–80% is a good balance.
JPG can’t store transparency, so transparent areas are filled with this colour.

Why Compress Images?
To compress an image, lower its quality setting, save it in an efficient format such as WebP, and scale it down if it is wider than it needs to be. A good starting point is 60–80% quality. Teasoft's Image Compressor does all three in your browser: add your images, pick the format, quality and optional maximum width, click Compress images and download the smaller files.
Phone cameras and screenshots produce files that are far bigger than most uses need. A single photo can be several megabytes, which is slow to upload, too big for many email attachments and heavy on a web page. Compressing the image makes it smaller while it still looks fine at the size people actually view it.
There are three ways to shrink an image, and this tool gives you all of them:
1. Lower the quality. Lossy compression discards detail the eye barely notices. This is the biggest saving for photos.
2. Choose a more efficient format. WebP is usually smaller than JPG or PNG at similar quality. JPG is smallest for compatible photos. PNG keeps exact transparency.
3. Reduce the dimensions. A 6000 px photo shown at 1200 px wide wastes most of its pixels. Limiting the width removes them.
Common reasons to compress images:
- You need photos small enough to email or attach to a form.
- A website, online store or portal rejects files over a size limit.
- Your pages load slowly because of heavy images.
- You are running out of phone, computer or cloud storage.
- You want a folder of images to be smaller before sharing or backing up.
- You are preparing images for a blog, newsletter or presentation.
What each setting does:
| Setting | What it does | When to use it |
|---|---|---|
| Quality | Lower values make smaller files with more compression. Default is 70%. | Almost always. 60–80% is a good balance. |
| Save as | Keeps the format, or switches to JPG, PNG or WebP. | WebP for the smallest web files, JPG for compatible photos, PNG for exact transparency. |
| Limit width | Scales images wider than your limit down to it. Smaller images are left alone. | Big phone or camera photos, or any image bigger than it will be shown. |
| Background | Fills transparent areas when saving as JPG. | Only when saving a transparent image as JPG. |
Good to know
- Compression is lossy. Lower quality means smaller files but some lost detail. Keep your originals until you've checked the results.
- PNGs are reduced to fewer colours. That is how PNG gets smaller, and it works very well for logos, icons and screenshots. A photo saved as PNG can still be big, and gradients can show banding at low quality. For photos, switch Save as to WebP or JPG.
- Don't compress the same file over and over. Each lossy pass removes a little more detail. Compress once from the original.
- Some images barely shrink. Files that are already small or heavily compressed may not change much. Check the size after compressing.
What You Can Do With This Compressor
- Control the quality. The slider starts at 70%. Lower values make smaller files, and 60–80% is a good balance for most images.
- Choose the output format. Keep the original format, or save as WebP, JPG or PNG.
- Limit the width. Set a maximum width in pixels. Wider images are scaled down, narrower ones are left untouched.
- Compress in bulk. Add up to 50 files at once, each up to 100 MB, and download them all as one ZIP.
- Transparency handled. Keep it with WebP or PNG, or choose a background colour to fill transparent areas when saving as JPG.
- Private by design. Files are processed in your browser and never uploaded to a server, which matters for personal photos, IDs and client work.
- Add files your way. Drag and drop, browse, or paste with Ctrl+V.
- No sign-up, no watermark, no fees.
- Works on any device. Windows, Mac, Linux, Android and iPhone, in any modern browser.
Which Image Tool Should I Use?
Use the Image Compressor when your goal is a smaller file. If your real problem is the format (a site won't accept the file type, or you want WebP for a website), use a converter. Converters accept more input formats, such as HEIC, SVG, PSD, TIFF and PDF, which the compressor does not.
How to Compress Images (3 Steps)
Add your images
Drag and drop your files, click browse, or press Ctrl+V to paste. You can add up to 50 JPG, PNG, WebP, GIF, BMP or AVIF files, each up to 100 MB.
Choose your settings
Open Settings. Pick the format (WebP for the smallest web files, JPG for photos, PNG when you need exact transparency). Keep quality around 60–80%. If your photos are very large, set a maximum width.
Compress and download
Click Compress images, check the sizes, then save each file or use Download to get everything in one ZIP.
Tip: if a file is still too big, lower the quality a little or set a smaller width, then compress again from your original (not from the compressed copy).
Which Settings Should I Use?
| Goal | Save as | Quality | Limit width |
|---|---|---|---|
| Email attachments | JPG | 60–75% | 1600 px |
| Photos for a website or blog | WebP | 70–80% | 1200–1600 px |
| Full-width website banners | WebP | 70–80% | 1920 px |
| Logos, icons and screenshots | PNG or WebP | 70–85% | Leave empty |
| Form or portal with a size limit | JPG | 50–70%, check the size | 1200–1600 px |
| Storage and backups | WebP or JPG | 70–80% | Leave empty |
These are starting points, not guarantees. Check the size and the look of the result, then adjust.
Which format should I choose?
| Choose | When |
|---|---|
| Same as original | You want to keep each file’s format and just make it smaller. |
| WebP | The images are for a website and every modern browser can show them. Usually the smallest. |
| JPG | Photos that must open everywhere (email, print services, upload forms). Transparent areas get a background colour. |
| PNG | Graphics that need exact transparency. Colours are reduced to make the file smaller. |
How to get an image under a size limit (for example 200 KB or 1 MB):
This tool does not target an exact file size, so use this routine: set a maximum width that suits the image (the width gives the biggest saving), save as JPG or WebP, start at 70% quality, then check the size. If it is still too big, lower the quality in steps of 5–10% or reduce the width, and compress again from your original.
Tips for compressing in bulk
- Keep the original files until you've checked the compressed versions.
- Use one setting for the whole batch. If some images need different treatment (for example detailed product photos), compress them separately at a higher quality.
- Compress from the original each time, not from an already compressed copy.
- Have HEIC, SVG, PSD, TIFF or PDF files? Convert them first with Images to JPG or Images to WebP, which accept those formats.
Frequently Asked Questions
How do I compress an image?
Open Teasoft's Image Compressor, add your images, choose the format and quality (60–80% works well for most), optionally set a maximum width, click Compress images and download the smaller files individually or as a ZIP.
How can I reduce the size of an image without losing quality?
You can't remove all loss, but you can reduce size with little visible change. Keep quality around 70–80%, save as WebP or JPG, and limit the width to the size you actually need. At these settings most photos look nearly identical but are much smaller.
Which formats can I compress?
JPG, PNG, WebP, GIF, BMP and AVIF, up to 50 files per batch and 100 MB each. For HEIC, SVG, PSD, TIFF or PDF files, convert them first with Teasoft's Images to JPG or Images to WebP converter.
What quality setting should I use?
The default is 70%, and 60–80% is a good balance for most images. Go higher (85–90%) for detailed photos you will print or zoom into, and lower (50–60%) only when you need the smallest possible file.
Which format gives the smallest file?
WebP is usually the smallest for websites. JPG is smallest for photos that must open everywhere. PNG is best for exact transparency and sharp graphics, and it gets smaller through colour reduction.
What does the "Limit width" setting do?
It scales down any image wider than the value you enter, in pixels, and keeps the proportions. Images that are already narrower are left as they are. Reducing the width is often the biggest saving for large photos.
Does compressing reduce image quality?
Slightly, because the compression is lossy. At 70–80% the difference is usually hard to see at normal viewing sizes. Keep your originals in case you need full quality later.
How do I compress an image to 100 KB, 200 KB or 500 KB?
The tool doesn't target an exact size, but you can get there in a few tries. Set a smaller maximum width, save as JPG or WebP, start at 70% quality and check the file size. Lower the quality a little and compress again from your original until it fits.
What happens to PNG files?
PNGs are made smaller by reducing the number of colours. This works very well for logos, icons and screenshots. For photos, switch Save as to WebP or JPG to get a much smaller file.
What happens to transparent backgrounds?
They are kept when you save as PNG or WebP. JPG can't store transparency, so transparent areas are filled with the background colour you choose.
Why didn't my file get much smaller?
It may already be small or heavily compressed. Try a lower quality, limit the width, or switch the format to WebP or JPG.
Why is my compressed file bigger than the original?
It can happen if the original was already well compressed, or if you changed to a format that suits the image less (for example a photo saved as PNG). Switch Save as to WebP or JPG, or lower the quality.
How many images can I compress at once?
You can add up to 50 files in one batch, each up to 100 MB.
Are my files uploaded to a server?
No. Compression happens in your browser, and your files are never uploaded.
Can I compress images on my phone?
Yes. The tool works in the browser on Android, iPhone, tablets and computers. You do not need to install an app.
Is the Image Compressor free?
Yes. It is free, with no sign-up, no watermark and no hidden fees.
