Compress images to a target size — fit photos under 100KB, 500KB or 1MB

Shrink photos under a target size like 100KB, 500KB or 1MB, keeping the best quality that fits and lowering resolution only if needed. In-browser, no upload.

Image Format Converter · JPG, PNG, WebP

Convert many photos to JPG, PNG or WebP at once and, if you like, shrink them by the long edge. iPhone HEIC, AVIF, GIF and BMP are read too. Everything happens inside this browser, and you can download each result or all of them as one ZIP.

Save as

JPG best for photos and opens anywhere · PNG lossless and keeps transparency · WebP smaller than JPG at the same quality

At 80–90 the difference is hard to see while the file gets much smaller.

Size (long edge)

Smaller photos are never enlarged, and the aspect ratio is kept.

HEIC to JPG · iPhone Photos

Turn HEIC photos taken on an iPhone into JPGs that open on Windows, Android and any upload form. Add as many as you like at once; nothing is uploaded to a server. Metadata such as location (GPS) is not carried into the result.

Size (long edge)

Safari reads HEIC natively. Other browsers download a HEIC decoder (about 1.4MB) once and decode on this device.

Compress to a Target Size in KB

Shrink photos to fit upload limits like "under 500KB" or "under 1MB". It finds the best quality that fits and lowers the resolution a little at a time only when quality alone isn't enough. Photos already under the target are left untouched.

Target size (at most)

1KB is counted as 1,024 bytes, the same way Windows Explorer and most upload limits count.

Max size (long edge)

Reducing the size first gives better quality at the same file size. For photos only viewed on screen, 1920 is plenty.

Merge & Split PDF · Organize Pages

Combine several PDFs into one, or split a file into single pages or the ranges you choose. In the list below you can rotate pages, remove them and drag them into a new order. Photos you add become pages too. Files are never uploaded; everything is processed inside this browser.

Output

Pages are joined in the order shown in the list and saved as one PDF.

Each page becomes its own PDF; two or more are bundled into one ZIP.

Each comma-separated group becomes one PDF. Numbers follow the order in the list below, and "7-" means page 7 to the end.

PDF ↔ Image · PDF to JPG

Turn each page of a PDF into a JPG or PNG image, or combine several photos into one PDF. Handy when a form asks for a page as an image, or when you need to hand in phone photos of documents as a PDF. Conversion happens only inside this browser.

Direction
Save as

JPG small and opens anywhere · PNG keeps text edges crisp

Resolution

150 dpi is plenty for viewing on screen. Choose 300 if you'll print or zoom into small text. An A4 page at 150 dpi is 1240×1754 pixels.

Page size

Each photo is centered and scaled to fill the page. Landscape photos get a landscape page.

Margin
Photo quality

Normal 2480 px on the long edge — fine for A4 printing · Light 1600 px on the long edge — small for email and uploads

        FAQ

        Are my photos or PDFs uploaded to a server?
        No. Reading and rebuilding photos and PDFs happens entirely inside this browser, and your files are never sent anywhere. The only things fetched from the site are the HEIC decoder and PDF tools, downloaded once the first time you add a HEIC photo or a PDF — after that you can even go offline. The browser remembers only the last tab you opened and settings such as format and quality. Site-wide visit stats (page address and time on page) are counted anonymously, but they never include your photos or file names.
        My iPhone HEIC photos won't open on Windows.
        HEIC is the iPhone's default photo format, but the Windows Photos app and many websites can't open it without an extra extension. Put the photos in the "HEIC to JPG" tab and they become JPGs that open anywhere. To shoot JPG on the iPhone in the first place, choose "Most Compatible" under Settings → Camera → Formats.
        What quality should I use?
        For photos, a JPG quality of 80–90 is a safe choice: the difference is hard to see and the file often drops below half its original size. Screenshots full of text and crisp graphics like logos look cleaner as PNG. WebP is usually 25–35% smaller than JPG at the same quality.
        Can I fit a photo under a fixed size like 500KB?
        Pick a target in the "Compress to Size" tab. It finds the highest quality that stays under the target and, if lowering quality isn't enough, trims the resolution a little at a time. Handy for ID photos and document uploads with size limits. Photos already under the target are left as they are, since re-compressing would only cost quality.
        Are the capture date and location kept?
        No. Each photo is drawn onto a canvas and saved fresh, so EXIF data such as the capture date, camera model and location (GPS) is not included. That also makes it a handy way to strip your location before sharing a photo. Rotation is applied to the image before saving, so pictures won't end up sideways.
        How many photos can I do at once?
        Up to 200 at once. The real limit is your device's memory, so running many 48-megapixel photos on a phone may slow down or stall — shrink the long edge or add them in smaller batches. Safari on iPhone and iPad scales any photo over about 16 megapixels down to fit (a browser limit).
        The WebP button is disabled.
        Safari can display WebP images but can't create them. Chrome, Edge, Firefox and Samsung Internet can save WebP. Converting WebP to JPG or PNG works in Safari too.
        Can I merge PDFs or pull out just a few pages?
        Add your files to the "Merge & Split PDF" tab and choose "Merge into one" to get a single PDF joined in the order you added them. In the page list below you can drag pages (or use the ‹ › buttons) to reorder them, remove pages you don't need and rotate sideways pages. To pull out a few pages, type something like "3-5" under "Split by range"; list several groups separated by commas, such as "1-3, 4-6", and each group becomes its own PDF in a ZIP.
        How good is the quality when converting PDF to JPG?
        Pick the resolution in the "PDF ↔ Image" tab. 150 dpi is plenty on screen; choose 300 dpi if you'll print or zoom into small text. Text-heavy documents look cleaner as PNG than JPG. Each page is drawn at no more than about 33 megapixels (about 16 on iPhone and iPad) — up to A3 fits even at 300 dpi, so only larger drawings get scaled down.
        Can I turn several photos into one PDF?
        Choose "Image → PDF" in the "PDF ↔ Image" tab and add your photos: you get one PDF with one photo per page, in the order you added them. You can pick the page size (A4, Letter or matching the photo) and the margin, and iPhone HEIC photos work too. Photos are re-saved before they go in, so details such as the location (GPS) where they were taken are not kept in the PDF.
        Are bookmarks, links and form fields kept in the merged PDF?
        Everything you can see on the pages — text, images and tables — is carried over as is. Bookmarks (the outline) and links that jump to another page inside the document are not (links to web addresses are kept), and fillable form fields may no longer work as editable fields. Keep your originals and use the merged file separately.
        Does it work with password-protected PDFs?
        PDFs that ask for a password when opened can't be opened here. PDFs that open without one but carry security settings such as print or edit restrictions can only be converted to images — they can't be merged or split. There's no feature for removing security settings.
