GET THE RESULT YOU NEED
Compress images and photos for easier sharing
Make photos, screenshots and graphics smaller for upload forms, email and websites. Start with the original format and dimensions, then adjust quality, set a target size or allow resizing when needed.
- Choose one image or add a batch. Each image keeps its original format by default.
- Adjust JPG/WebP quality or choose a target size. Allow smaller dimensions only when your destination permits it.
- Process the images, compare the results and download individual files or one ZIP.
What to expect
A smaller file is not guaranteed. A PNG at its original dimensions may already be efficient. The Web ready preset converts to WebP and limits the longest edge to 1920 pixels; it is an optional choice for website images.
Can I compress images without resizing?
Yes. Resizing starts off on this page. Leave it off to keep the same pixel width and height. Changing JPG or WebP quality can still change visual detail.
Can I upload JPG, PNG and WebP together?
Yes. Keep original format processes each static image in its own format. A specific output format converts the whole batch to that format.
Can I set an exact file-size limit?
Yes. Choose 100 KB, 200 KB, 500 KB or a custom limit under Target file size. Allow smaller dimensions only if appropriate. Each result reports Target met or Above target; a fit is not guaranteed.
Does compression keep photo dates and metadata?
Preserve supported metadata is selected by default: EXIF dates, camera details and GPS are carried over, with orientation and dimensions updated. PNG text/dates and JPG comments stay when keeping their format. XMP, IPTC and original colour profiles are not transferred; embedded preview links are cleared during re-encoding. Choose Remove metadata to omit source metadata; this disables the original-file fallback. Downloaded filesystem dates may change.
HOW IT WORKS
How image compression works
Smaller files start with the right format. Here is how encoding, quality and your original image affect the result.
What does encoding mean?
Decoding turns the bytes in an image file into pixels that a browser can display. Encoding turns pixels back into a file, using the rules of JPG, PNG or WebP. It is not encryption. Our compression and conversion tools decode locally, draw the image onto a canvas and call the browser’s canvas.toBlob encoder. The browser supplies the codec, so results can vary between browsers.
How JPG compression works
JPEG commonly splits image information into small blocks, uses a discrete cosine transform to describe patterns within them, then rounds transform coefficients in a step called quantization. Coarser rounding saves space but discards detail. The remaining values are efficiently coded into bytes. Our quality control is passed to the browser encoder; it is not a percentage of original detail retained or a guaranteed percentage reduction. Repeated JPG re-encoding can introduce additional artefacts.
How PNG encoding works
PNG uses reversible filters on pixel rows followed by DEFLATE compression. These steps can represent the encoded pixels without JPEG-style quality loss. PNG ignores the quality slider. This tool uses the browser’s PNG encoder, rather than a dedicated palette-reduction optimiser, so an already efficient PNG may not get smaller. Resizing or colour handling before encoding can still change pixels; lossless encoding does not promise that the whole editing pipeline preserves the original file.
How WebP compression works
Lossy WebP predicts image regions from neighbouring pixels, transforms the difference and quantizes it before coding the result. The format also supports a separate lossless mode, but this tool requests browser WebP encoding with a quality setting and does not expose a guaranteed lossless mode. Transparency can be retained. A lower quality setting often reduces size, although sharp text and fine textures may suffer.
Why the original may be kept
After encoding, the tool compares byte sizes. With Preserve supported metadata selected, when format, dimensions and geometry are unchanged and the new file is not smaller, it keeps the original bytes. This avoids a larger replacement. A retained original also retains its metadata: use the Metadata Remover when privacy cleaning is the goal. ZIP download bundles the files without another lossy image-encoding step.
Where processing happens
Your selected image is processed on your device, without an image upload. Canvas exports are new files and may change embedded metadata or colour information. Keep a master copy for archival work. Animated PNG and animated WebP are rejected; these tools handle static images.
How target-size compression works
Choose 100 KB, 200 KB, 500 KB or a custom decimal-KB limit. For JPG/WebP, the tool tries quality values from your selected maximum down to 10% and refines a successful bracket with a bounded binary search. When you explicitly allow smaller dimensions, it can also try up to eight downsizing steps. PNG ignores quality. Exact resizer dimensions are preserved. Only a measured output within the byte limit is marked Target met; otherwise the smallest tested candidate is marked Above target. This is a bounded search, not proof of a globally optimal result.
Metadata choice
Preserve supported metadata is the default: EXIF dates, camera and GPS fields are copied, with orientation reset after decoding and dimensions updated. PNG text/dates and JPG comments stay within their format. XMP, IPTC and original colour profiles are not transferred; embedded preview links are cleared. Retained metadata is included in target-size measurements. Remove metadata omits source metadata and disables the original-file fallback. Filesystem download dates are separate.

GOOD TO KNOW
A few small details.
Better images start with the right settings.
Which format should I choose?
WebP is a useful starting point for website photos and transparent graphics. JPG suits photos when you need a JPEG file; transparent areas become white. PNG uses lossless encoding and keeps transparency, but often creates larger files.
Will compression change image quality?
JPG and WebP use lossy compression: lower quality usually means smaller files and more visible changes. Use Compare to inspect your result. PNG encoding is lossless, but resizing still changes pixels. PNG conversion can increase file size. This tool uses your browser’s image encoders, so results can differ between browsers.
Why is my image already small?
If the output uses the same format and dimensions but is larger than the original, we keep your original file. Changing formats or dimensions can still create a larger result; the actual size is always shown. The quality slider doesn’t affect PNG encoding.
Are there file limits?
Add up to 100 static images, 50 MB per image and 200 MB of original files per batch. Each image must be within 40 megapixels and 16,384 pixels on either side. Animated PNG and WebP are rejected to protect their animation. GIF, SVG, HEIC and AVIF aren’t supported in this version. Large batches depend on your device’s memory.
Are my images uploaded or saved?
This tool processes selected images locally in this browser tab and doesn’t send image files to a server. Your site’s hosting, analytics or other plugins may separately collect normal website visit data. Download results you want to keep before clearing the list or leaving. Re-encoding generally removes file metadata; an original file kept because it was smaller retains its existing metadata. This isn’t a metadata sanitization tool.
