Compress Any Image to an Exact File Size.

The image is drawn to a canvas and encoded once at the lowest acceptable quality. If that already fits under your target, the encoder quality is bisected to find the highest quality that still fits — so you keep as much detail as the size allows. If quality alone cannot reach the target, the pixel grid is scaled down and the search runs again, repeating until the file fits.

No. There is no upload endpoint in this application. Files are read with the browser File API, decoded with createImageBitmap, drawn to a canvas and re-encoded with canvas conversion. All of that happens in this tab, on your device. You can disconnect from the internet after the page loads and the tool will still work.

There is no file-size limit imposed by the tool, but anything above 15 MB is decoded at full resolution in memory and can exhaust a device with low RAM. If your browser tab crashes, close other tabs and try a smaller source image. Camera originals in the 20–40 MB range usually work fine on a laptop.

Yes. Modern browsers decode HEIC through the same canvas pipeline, and because most upload forms only accept JPEG, the tool converts to JPEG (or WebP) automatically while it compresses. The result downloads as a .jpg you can upload anywhere — a job portal, an email attachment or a marketplace listing.

Those services work — by sending your file to their servers. This one never uploads anything: decoding, quality search and re-encoding all happen inside this browser tab. That also means no daily quota, no account, no file-size ceiling imposed by an upload form, and nothing left on a third-party server afterwards.

Some, by definition — a smaller file holds less information. What you keep is control: the tool searches for the highest quality that still fits your byte budget instead of guessing. Use the before/after slider on the actual pixels to judge the result, and switch formats to WebP if you want more detail at the same size.

Yes, automatically. Re-encoding through a canvas drops EXIF metadata — GPS coordinates, camera serial number, lens data and timestamps do not survive the trip. If a form has ever rejected your photo for being “too large”, the metadata was often part of what made it large.

Job portals, council forms and marketplace listings set byte limits like 50 KB, 100 KB or 200 KB so their storage stays cheap and pages load fast. Those limits are stated as sizes, never as quality settings — which is exactly why this tool takes a byte count as its input. Pick the limit your form states and the file lands under it.

Yes — drop a whole folder or select multiple files. Every image is queued and compressed to the same target one after another, then everything downloads back as a single ZIP archive. There is no batch limit; the only constraint is your device’s memory while the queue runs.

Yes — this page is an image compressor to 50kb, an image compressor to 100kb and an image compressor to 200kb: pick the target size, drop the photos, and every file comes back at that exact number. If a form says “maximum 50 KB”, choose 50 KB and the result lands under it.

It can also be an image compressor to 1mb, an image compressor to 500kb and an image compressor to 20kb — any target from 5 KB to 5 MB works the same way, including unusual custom values like 175 KB.

It is this tool: use it as a photo size reducer 20 kb for avatar and form fields, a photo size reducer 50 kb for job-portal uploads, or a photo size reducer 100 kb for marketplace listings. Pick the KB target, drop the photo, download the smaller file — nothing is uploaded anywhere.

Yes — you can compress image online free on this page with no account, no watermark and no daily cap. “Free” means the whole tool: unlimited files, every preset, batch mode and the comparison slider, all running in your own browser.

Set the Target Size to the KB number your form asks for — 20 KB, 50 KB or 100 KB — press Compress, and the encoder works backwards from that byte count until the file fits. No quality guessing, no second guessing: the result reports the exact size it saved.
