Why use this online image compressor?
See the actual savings
See the original and the compressed size for every image, so you know exactly what you saved.
Compress images in batches
Add up to 100 images, keep adding files after a batch, and download each result or package them into one ZIP.
Keep files on your device
Compression and ZIP creation run in your browser, so supported JPG, PNG, GIF, WebP, SVG, and TIFF files are not sent to ImageNow servers.
How it works
- Select or drop up to 100 JPG, PNG, GIF, WebP, SVG, or TIFF images.
- Click Compress images and every selected file is compressed in turn.
- Review the file-size savings, then download one image or all results as a ZIP.
Reduce image size for websites, uploads, and sharing
Large photos and graphics take longer to upload, send, and display. Reducing image size before publishing product photos, blog images, portfolio work, email attachments, or form uploads can improve load time and make files easier to share without changing their format.
Each image format needs a different compression method
JPG and WebP are re-encoded. PNG is rewritten by the browser and may shed metadata, while GIF keeps its animation but reduces and optimizes its colors and frames. SVG removes redundant vector markup without becoming a bitmap, and TIFF uses lossless ZIP compression. The source content and any previous optimization determine the actual savings.
Your file keeps its format and dimensions
The output keeps the source format and pixel dimensions — an animated GIF stays animated, an SVG stays vector. When a picture is already tightly compressed, you get the original back.
Everything happens in your browser
You can process up to 100 images per batch, with a 100 MB limit for each file. The files stay in the current browser session and are not uploaded. Re-encoded images may omit EXIF, editor, and other non-visual metadata; if an already optimized original is kept because it is smaller, that original file remains unchanged.
Frequently asked questions
How do I compress an image online?
Select or drop supported JPG, PNG, GIF, WebP, SVG, or TIFF images, click Compress images, review the original and compressed sizes, and download the results. No account or software installation is required.
Does compressing an image reduce its quality?
JPG and WebP re-encoding and GIF color reduction may remove some image data. PNG is rewritten by the browser and may lose metadata, while SVG and TIFF use structural or lossless compression. ImageNow aims to keep images clear for everyday web, upload, and sharing use.
Which image formats can I compress?
This page compresses JPG and JPEG, PNG, GIF, WebP, SVG, TIF, and TIFF images. Each output keeps the same file format as its source image.
Can I compress multiple images at once?
Yes. You can add up to 100 images, compress the current batch with one action, continue adding files, and download completed results individually or together as a ZIP.
What is the image file-size limit?
Each supported image can be up to 100 MB. Browser memory, image dimensions, animation frames, and TIFF pages can still affect very large files, so an individual file may fail without stopping the rest of the batch.
Are my images uploaded to a server?
No. Image decoding, compression, previews, and ZIP creation happen locally in your browser. Closing or refreshing the page clears the current working session.
Why did my image save little or no space?
An image that was already optimized may not become smaller when re-encoded. File format, image detail, color count, existing quality, and metadata all affect the result. ImageNow keeps the original when the compressed attempt would be larger.
Does compression change image dimensions or format?
The compressor keeps the original image format and dimensions whenever the browser can safely process them. Animated GIF remains animated, SVG remains vector, and TIFF remains TIFF. Extremely large dimensions or complex multi-frame files may still reach browser memory limits.
