Compress an image in the browser
Choose the format for the recipient
This page opens the image studio with JPEG at about 60 percent quality, which is a reasonable start for a photograph you want to email. It is not a promise of a particular file size. Export, look at the picture at 100 percent, and raise the quality if edges you care about have broken into blocks. PNG is the better export when the image is a screenshot of text or a diagram with hard edges. WebP is smaller where the recipient’s software can show it. If this browser cannot encode the format you picked, the download falls back to PNG. Read the real file type before you rename it to .webp. The sample poster is a 640 by 400 PNG you can practice on.
Crop and resize before you spend quality on pixels you will throw away. A long edge is enough when you only need the picture to fit a message. An exact size is for a slot that demands dimensions. The work is local. NexTool does not upload the photo. Keep the camera original until the message is sent, because mail software may resize the attachment again and you cannot ask this page for the file later. Several pictures belong on batch compress, which builds a ZIP. A PDF scan belongs on PDF compress, which redraws pages rather than exporting a single picture. The image guide walks through that choice.
What to check
The file stays in this browser. NexTool does not upload it and does not keep a copy after you leave the page. Download the result and check it before you send it on. If the tab runs out of memory, the job stops and the original is still the one on your computer.
Look at faces, small type, and fine lines. If the export is softer than the job allows, raise the quality and export again from the original, not from the new file. Renaming a PNG to .jpg does not compress it. The studio has to encode it. A watermark, if you need one, is a separate page and should be applied to a copy you can spare, not to the only original.
A session that does not throw the original away
Open image compress with the photograph you intend to send, not with the only copy if you can avoid it. The page starts near 60 percent JPEG because that is a practical email size for many photos, not because 60 is a rule. Crop away the empty margin first so you do not spend quality on pixels you will not keep. Export, open the new file at 100 percent, and look at eyes, small type, and edges. If they break into blocks, raise the quality and export again from the camera original. The sample poster is 640 by 400 pixels and is safe to practice on. Your photo is not uploaded. The download is the only copy this site will ever hand you.
Screenshots of text and diagrams with hard edges belong in PNG, which this studio can still export. WebP is smaller when the recipient can open it. If the browser cannot encode the format you chose, the file comes back as PNG. Read the type before you rename the extension. A PDF page is not this tool. Use PDF compress when the scan is already a PDF, and batch compress when several pictures should become one ZIP. The image guide is the longer note. Ads on this site, when they are filled, do not receive the picture. The picture never leaves the tab except as the file you download.
