COMPRESS IMAGE

Compress images in your browser

Compress PNG, JPEG, WebP, or AVIF images locally with quality, palette, and auto-smallest controls, then compare actual output bytes.

Reduce image bytes locally without uploading the source. Start with Auto smallest or choose a format and quality, then inspect the actual result before downloading.

01

Add an image

Choose, drop, or paste a PNG, JPEG, or WebP file. The source stays in the current browser tab while you work.

02

Choose how to compress

Auto smallest encodes supported candidates and keeps the smallest actual file. A fixed JPEG or WebP format lets you control quality; palette PNG lets you control the colour count.

03

Generate and verify

Generate the result, compare its format, dimensions, and bytes with the source, then download only after the preview meets your needs.

Drop images into the queue

Everything runs in this browser.

Add, drop, or paste up to 12 PNG, JPEG, or WebP images.

Quality and dimensions

Lower quality can reduce JPEG, WebP, or AVIF bytes. Reducing pixel dimensions can save more, but enlarging later cannot restore discarded detail.

Transparency and metadata

JPEG fills transparent pixels with the selected background. Re-encoding removes source metadata; keep the original when metadata matters.

When this task helps

Compress for delivery, not just a smaller number

Common questions

Will compression always make an image smaller?

No. A source that is already optimized can stay similar or become larger in another format. Check the measured output bytes before downloading.

Does a lower quality number mean the same thing in JPEG and WebP?

No. Quality scales are encoder-specific. Compare the visible result and file size instead of treating equal numbers as equal quality.

Can compression preserve every pixel and all metadata?

Lossy output can change pixels, and every export here is re-encoded without source metadata. Keep the original when either matters.

Resize images by pixels or percentageResize PNG, JPEG, or WebP images by exact pixels or percentage with aspect ratio, fit, crop, and no-upscale controls in your browser.Compress an image to a target sizeSet a best-effort KB ceiling, run bounded quality and dimension adjustments locally, and see whether the image reached the requested size.Convert images to PNG, JPEG, WebP, or AVIFConvert PNG, JPEG, or WebP locally to PNG, JPEG, WebP, or browser-supported AVIF, with explicit transparency and fallback guidance.Crop images with a visual frameCrop PNG, JPEG, or WebP images locally with a draggable frame, exact coordinates, and 1:1, 4:3, or 16:9 presets.Rotate or flip images in your browserRotate PNG, JPEG, or WebP images by 90 degrees or an exact angle, expand the canvas, and flip horizontally or vertically.Mirror an image horizontally or verticallyMirror PNG, JPEG, or WebP images horizontally or vertically in your browser, then inspect directional details before export.Pixelate an image with adjustable blocksPixelate PNG, JPEG, or WebP images locally with an adjustable block size and inspect the complete result before download.Convert an image to grayscale or black and whiteConvert PNG, JPEG, or WebP images to grayscale or threshold black and white locally, then inspect contrast before export.Add a watermark to an imageAdd a text or PNG, JPEG, or WebP image watermark locally, then adjust bottom-right size and opacity before export.Batch resize images in your browserResize up to 12 PNG, JPEG, or WebP images locally with shared settings, inspect each result, and download completed files as a ZIP.
