Compress an image to 200 KB
At 200 KB there is room to keep a photo reasonably detailed. This page sets the target to 200 KB and outputs JPEG; it lowers quality first and shrinks the pixel dimensions only if that is not enough, which happens more often with large or very detailed pictures. The exact size is shown after compression.
Runs in your browser
Free, no sign-up. Decoding, resizing and re-encoding happen in your browser on a canvas. The images are not uploaded; the tool only records anonymous actions such as 'compress' or 'download', never file names or sizes.
Drop images or click to upload
JPEG, PNG, WebP, GIF, BMP • Max 50 MB per file • Up to 20 files
Every file is scanned for security threats before processing

Target file size
The tool picks the highest quality that fits, and only shrinks the pixel size if the lowest quality is still too big. The Quality slider is not used.

How to use the Image Compressor
- Drop your image onto the upload area (JPEG, PNG, WebP, GIF or BMP).
- The Target file size box already shows 200 KB and the output is JPEG, which can be tuned by quality. Change the number if your upload field asks for a different limit.
- Press Compress. The tool tries lower qualities first, then shrinks the pixel dimensions if quality alone is not enough.
- Read the line under the file: it states the exact byte size and whether the target was met.
- Download the result and check it still looks acceptable before you upload it.
Worked example
Sample data
A generated 3000 x 2000 test photo (JPEG, 2,386,343 bytes), target 200 KB.
197,726 bytes (under the 200 KB target), 2388 x 1592 px JPEG.
Measured in this tool on a generated, deliberately noisy test photo, which is harder to compress than most real pictures. Your final size and dimensions will differ.
Good to know
Here 1 KB is counted as 1,000 bytes. Your computer may show sizes in 1,024-byte units, which reads about 2% smaller, so leave a little room if a form is strict.
How it works
How the compression works
The browser decodes each image onto a canvas at the target size and encodes it again in the format you chose. Smaller pixel dimensions and a lower quality value both reduce the file size; resizing usually saves far more than quality alone.
Quality applies to JPEG and WebP output. PNG is lossless, so the quality slider does not change a PNG: to shrink a PNG, reduce its dimensions or switch the output to WebP or JPEG.
saved % = (original size - compressed size) / original size x 100
Choosing a format
JPEG suits photographs. WebP is usually smaller than JPEG at similar quality and supports transparency, but very old software may not open it. PNG suits screenshots, logos and anything that needs exact pixels or transparency.
Because the image is redrawn on a canvas, transparent areas become black if you save as JPEG, which has no transparency. Pick PNG or WebP to keep transparency.
What gets removed
Re-encoding keeps only pixel data. Camera EXIF data such as GPS location, device model and timestamps is not carried over, which is useful before publishing a photo but means you cannot recover it from the compressed copy.
Animated GIFs lose their animation: only the first frame is processed. SVG files are rejected on purpose because they can contain scripts.
When the result is bigger
The tool does not keep the original when the new file is larger. An already well-optimised JPEG saved at 100% quality, or a WebP converted to PNG, can grow. If Saved shows no gain, lower the quality, reduce the dimensions or keep your original.
Inputs, outputs and limits
Inputs
- JPEG, PNG, WebP, GIF or BMP images (TIFF is accepted but depends on your browser being able to open it)
- Quality 1-100% (default 80%)
- Output format: JPEG, PNG or WebP
- Optional maximum width and height in pixels, with Maintain aspect ratio on or off
Outputs
- One compressed image per input, in the chosen format
- Original size, compressed size and percentage saved for each file
- Download for a single file or all files at once
Limits
- Up to 20 files per batch and 50 MB per file.
- Images larger than 16,384 x 16,384 pixels are rejected.
- Quality has no effect on PNG output.
- Animated GIFs become a single still image; SVG is not accepted.
- Very large batches depend on your device's memory, since every image is decoded in the browser.
Processing
- Decoding, resizing and re-encoding happen in your browser on a canvas. The images are not uploaded; the tool only records anonymous actions such as 'compress' or 'download', never file names or sizes.
Frequently asked questions
Will the dimensions change?
Possibly. If lowering quality to the floor is not enough, the tool scales the picture down. The file card lists the final dimensions whenever it did.
Is JPEG the only choice?
On this page the output starts as JPEG. Under Settings you can switch to WebP, which is often smaller at the same quality.
Why is the result lower than 200 KB?
The search picks the best quality that is not above the limit, so the result sits at or under it.
Are my files kept anywhere?
No. Everything stays in your browser tab and is gone when you close it.
