Compress JPG, PNG and WebP images by quality or straight to an exact KB target. Compare before and after side by side, process a whole batch at once, and keep every file on your own device.

One focused tool — no clutter, no watermarks, no upload queue.
Type 100 KB, 200 KB, or any limit a form imposes. Quality is tuned automatically by binary search until the file lands just under your number, so uploads stop getting rejected.
A drag-to-compare slider puts the original and the compressed version on top of each other at full size, so you can confirm the quality is acceptable before you commit.
One slider covers JPG and WebP. 80% is the sweet spot for most photographs, typically cutting file size by more than half with no visible difference on screen.
Turning a heavy PNG photo into a JPG, or anything into WebP, often saves more than compression alone. Pick the output format and both happen in a single pass.
Drop in dozens of images, apply one setting, and download the whole optimised set as a single ZIP archive. Ideal for prepping a gallery or a product catalogue.
Every byte is encoded by your browser. Nothing is uploaded, so compressing a folder of client photos or internal screenshots carries no disclosure risk.
No account, no installs, no waiting on a server.
Drag in one photo or a whole batch. JPG, PNG, WebP, GIF, BMP, TIFF and AVIF are all accepted.
Drag the quality slider for a quick squeeze, or switch to file-size mode and type the exact KB limit you have to meet.
Check the before-and-after view, then save each image or grab the entire batch as one ZIP file.
How to shrink photos for the web, email, and upload forms while keeping them looking the way you intended.
Application portals that reject anything over 2 MB, email attachments that bounce, product pages that load slowly on mobile — nearly every file-size problem is solved by sensible compression. This image size compressor handles JPG, PNG and WebP, works on single files or whole batches, and gives you both a quality slider and a hard KB target so you can match whatever rule you have been handed.
Quality mode is best when you care about how the picture looks and only broadly about size: set 80%, check the comparison view, and move on. Target-size mode is for the opposite situation, where a form dictates an exact ceiling and the picture simply has to fit. Behind the scenes the target mode repeatedly re-encodes at different quality levels, narrowing in until it finds the highest quality that still fits under your limit.
JPG remains the safest choice for photographs and is supported everywhere. WebP typically produces files 25–35% smaller than JPG at matching visual quality and supports transparency, making it the better pick for modern websites. PNG should be reserved for graphics, screenshots, and anything needing crisp edges or an alpha channel, because it stores photographs very inefficiently.
Compression services normally upload your images, process them on a server, and store the result for you to fetch. This one uses your browser's own encoder instead, so the picture is read from disk, re-encoded in memory, and written back to your downloads folder. That keeps unreleased product photos, client work, and personal images entirely under your control.
The practical details, including how your privacy is protected.
Switch to file-size mode, type 100 into the target field, and keep the unit on KB. The compressor runs a binary search over encoder quality — and will gently reduce dimensions if you allow it — until the exported file sits just below 100 KB. The same approach works for 50 KB, 200 KB, or any other limit.
For typical photographs, JPG at 80% quality usually saves 50–70% versus an unoptimised original, and converting to WebP often saves another 25–35% on top. Screenshots and flat graphics compress even harder. Files that were already optimised will shrink much less, which is normal and a sign the original was well prepared.
Not at sensible settings. JPG and WebP are lossy, so some data is discarded, but at 75–85% quality the difference is invisible at normal viewing sizes. Use the comparison slider to judge for yourself, and raise the quality if you spot artefacts in smooth skies or skin tones.
PNG is a lossless format, so quality settings do not apply the way they do to JPG. The biggest saving for a PNG photograph is converting it to JPG or WebP, which this tool does in the same step. For logos, screenshots, and images with transparency, keep PNG or move to WebP, which supports transparency at a much smaller size.
No. Everything runs inside your browser tab using the HTML5 Canvas and File APIs. Your photos are read from disk, processed by your own device, and saved straight back to your downloads folder. No file is ever transmitted to us, so there is nothing for us to store, log, or share.
It is completely free with no account, no watermark, and no cap on how many images you process. Because the work happens on your hardware rather than ours, there are no server bills to pass on to you.
Every tool runs in your browser — nothing is uploaded, and nothing costs anything.
Resize by pixels or percentage, or hit an exact KB or MB target.
Upscale photos 2x–8x or to exact pixels with smooth multi-step enlargement.
Drag to crop, snap to any aspect ratio, or enter exact pixel coordinates.
Turn photos 90°, 180°, or straighten by any custom angle in bulk.
Mirror photos horizontally, vertically, or both — single files or batches.
Read camera, exposure, GPS and every embedded tag from any photo.
Strip GPS, camera and timestamp tags without recompressing your photo.
